Detailed Description

The present disclosure provides methods and suture constructs for securing tissue (e.g., soft tissue) to bone.

Suture constructs, suture anchor assemblies, and methods for securing soft tissue are disclosed herein. The suture construct may include locking sutures and uneven sutures of the repair. The suture construct may include one or more small loops or apertures at the distal end. The suturing feature may include a joint at the proximal end that terminates in a tapered portion/region. The suture construct can be pre-loaded onto either a soft suture anchor or a hard anchor (fixture).

The rugged suture may include multiple enlargements, which may be a series of bumps, barbs, knots, beads, knobs, protrusions, ridges, or similar structures (or combinations thereof) added as a core to the coreless suture. The enlarged portions may be knotted and/or arranged as a series of ridges (chains) along the inner wire. The suture may be made up of a central strand of cored suture (internal thread) having fixed knots, beads and/or spinous processes at defined intervals, similar to bathroom drain chains. The spinous processes may be symmetrical or asymmetrical with the tapered end towards the band (cinch). An inner wire having an enlarged portion may be disposed within (e.g., inserted into) a coreless suture to form a suture having a core with irregularities. The protuberance can be a knotted protuberance to provide at least one point of ratchet. The enlarged portion may be a portion of the inner strand or wire that is covered by a coreless suture (outer sheath).

The loop may be provided at one end of the rugged suture. Rugged sutures can be used to form a bridging sheath (knot) around the tissue. Rugged sutures can be used to form knotless, closed, self-locking rings around tissue. Once the closed loop is formed, the enlarged portion of the suture construct prevents the suture construct from sliding (backing) backwards. The tab portion may be provided with a plurality of enlargements on a side near the loop at the distal end of the suture.

Fixation of soft tissue is achieved by using at least one suture construct around or through the tissue without the need for a nitinol wire loop or similar device. The tapered portion/region of the construct allows the suture construct to be retrieved after passing through tissue. After forming a railhead hitch or band suture and/or locking with an enlarged portion near the loop, the suture construct may be secured into the bone with additional fixation devices, such as one or more suture anchors. This configuration may be used with either knotless or knotted fixation devices. Tissue fixation is achieved with an overall reduction of steps and a minimum of knotting requirements.

According to one embodiment, the suture construct may comprise a suture having enlarged portions in the form of a series of bumps, barbs, knots, beads, knobs, or similar structures (or any combination thereof) added as a core to a coreless suture. The enlarged portions may be knotted and/or arranged as a series of ridges (chains) along the inner wire.

The suture construct may be constructed of a cored stitched central strand with enlarged portions (i.e., fixed knots, beads, barbs and/or spinous processes at defined intervals), similar to a bathroom drain chain. The spinous processes may be symmetrical or asymmetrical with the tapered end towards the band (cinch). An internal wire having an enlarged portion may be inserted into the coreless suture to form a suture having an uneven core. The enlarged portion may be a knotted protuberance to provide at least one ratchet point. The enlarged portion is the portion of the inner strand that is completely covered by the coreless suture (outer sheath). The enlarged portion is thicker than the coreless suture, i.e., the enlarged portion has an outer diameter that is larger than an outer diameter of the coreless suture.

According to embodiments, the tab portion may be provided with a plurality of enlargements at one side near the loop at the distal end of the suture. The shuttle is pre-threaded through the loop to shuttle the suture tail back through the loop after passing through the soft tissue. Once the suture is passed through the soft tissue, the tail is passed through the loop using a shuttle by folding and shuttling the tapered end through the loop. The suture is then pulled through until it is fully cinched. When it is tightened, the enlarged portion, which is thicker than the coreless suture, is pulled into the loop and prevents the suture from backing up.

According to another embodiment, the suture construct may comprise: a flexible strand having one or more small loops or orifices at its distal end, a tapered proximal end (tapered tail), and a junction region disposed between the small loops and the tapered proximal end. The joint region is provided with a plurality of enlarged portions within the coreless suture at the distal end of the suture (completely covered by the coreless suture). The enlargement may be any knot, bead, protuberance, protrusion, knob, or similar element, or a combination thereof. The enlargement may be formed by any method known in the art, such as knotting, braiding, weaving or gluing, to provide a series of beads on the cord, attaching a series of beads or similar elements to the cord, and the like.

In one embodiment, the suture construct comprises a string of enlarged portions that are added to the coreless suture as a core (rugged core). The enlarged portion may be knotted or provided as a series of ridges (chains) or as a series of unidirectional barbs or similar structures along the inner wire. The enlarged portion and/or the inner wire may be formed of various materials, such as metal or plastic, or a suture material, among others. An internal wire having an enlarged portion is disposed (e.g., inserted) within the coreless suture to form a suture having an uneven core.

The enlarged portion may have various designs and/or configurations such as a circular, triangular, oval or cylindrical cross-section, as well as many other shapes known in the art. The enlarged portion may be disposed at various locations along the length of the inner wire. The enlarged portions may be disposed in various directions along the length of the inner wire, for example, a bidirectional enlarged portion or a multidirectional enlarged portion. The enlarged portion may be provided as a one-way barb.

In another embodiment, the stitched construction may be comprised of a central strand of cored suture with fixed "spinous processes" at defined intervals, similar to a bathroom drain chain. The spinous process can be asymmetric with the tapered end toward the band (as described in detail below). After the working distance length is properly defined, the suture will be aligned with cored #2Same and then tapering to a smaller 2.0To facilitate loading in the strap mechanism and to form a knotless suture construct having a joint and a joint forming mechanism. Once the suture is passed through the soft tissue, the tail (tapered end) is passed through the aperture/opening at the distal end by shuttling it through the aperture/opening. The suture is then pulled through until it is fully cinched. When it is tightened, the thicker protuberance/spinous process engages the aperture/opening and locks the suture under tension, preventing the suture from backing and loosening.

The shuttle device may be pre-loaded onto the loop to load the tapered suture tail back through the loop after it has passed through the soft tissue. The flexible coreless strand may be a suture, tape, wire, or any flexible material known in the art. The shuttle device may be a suture passing instrument, suture passing device, shuttle/pulling device, loader, shuttle wire, or any other threading deviceInstruments, e.g. fiberLink^TMOr a nitinol ring. The central core may be a suture, tape, wire, or any flexible material known in the art. The central core may be flexible or rigid.

Once the flexible strand is threaded through the soft tissue, the tapered tail is threaded through the loop of the shuttling device by folding and shuttling the tapered end through the loop. The flexible strand is then pulled through until it is fully tightened. As it tightens, the enlargement from the thicker tab portion pulls into the loop and prevents the flexible strand from backing out.

The flexible strands may be standard braided coreless sutures, may be tapered, and may include three exemplary different widths throughout their length with one or more enlargements/nodules in one of the portions of the suture to create ridges or ridges. The suture may be provided with a locking mechanism, such as one or more small loops, eyelets, openings, slits, etc., to allow the suture to be pulled through until the enlargement (ridge/bump/protrusion/knot) engages and locks the suture under tension.

The ring is large enough to allow a portion of the tapered end and joint region to pass through it, and then lock onto the ring to form a band suture around the soft tissue. The flexible strands may be coreless to allow for the insertion of an internal wire having an enlarged portion, or in some applications, portions of the coreless strands may have a core. The loops may be formed by splicing or other methods known in the art, such as braiding, weaving, or gluing.

In another embodiment, the suture tightening strap comprises a coreless suture or sheathing envelope that houses (completely covers) an inner core, which is a smaller suture with enlargements (knots/beads/barbs, etc.). The suture may terminate in a loop to allow at least one rail hanger pocket to be formed. The enlarged portion provides a point of ratchet to prevent the rail hanger sleeve from slipping off.

Referring now to the drawings, wherein like elements are designated by like reference numerals, fig. 1-19 illustrate exemplary suture configurations 100, 200, 300, 400 (sutures 100, 200, 300, 400; suture configurations 100, 200, 300, 400; edge-to-edge knotless sutures 100, 200, 300, 400; knotless closure sutures 100, 200, 300, 400) of the present disclosure. Fig. 20-28 illustrate suture configurations 100, 200, 300, 400 as part of a suture anchor assembly 111, 112, 113, 114, 115, 116, 117 for securing a first tissue to a second tissue.

As described in detail below, each suture configuration 100, 200, 300, 400 includes a central strand 50 (first strand or filament; inner strand) of cored suture and an outer strand 10 (second strand or filament; outer strand; coreless suture) of suture overlying the central strand. The center strand 50 includes a plurality of enlarged portions 55, 155, 255, 355. In one embodiment, the outer strands 10 completely cover the central strand 50 and the enlarged portions 55, 155, 255, 355 in at least two directions (longitudinal and transverse).

The enlarged portions 55, 155, 255, 355 may include bumps, knots, beads, barbs, protrusions, or nubs, or any combination thereof. The enlarged portions 55, 155, 255, 355 may have various designs and/or configurations, such as circular, oval, or cylindrical, among many other shapes known in the art. The enlarged portions may be disposed at various locations along the length of the inner wire 50 (central strand 50). The enlarged portions may be disposed at various locations along a predetermined length of the inner wire 50 (i.e., along only a portion of the length of the central strand 50). The enlargements may be disposed in various directions along the length of the inner wire, such as bi-directional enlargements, wherein a first plurality of enlargements is oriented in a first direction relative to the longitudinal axis of the strand 50, and wherein a second plurality of enlargements is oriented in a second direction relative to the longitudinal axis of the strand 50, the first direction being different from the second direction. The enlarged portions may be formed at any angle to the surface of the central strand, for example, at a 45 degree angle to a tangent of the outer surface of the central strand. The enlarged portions may all be similar or different, i.e. may have similar or different shapes, forms and configurations. The enlarged portions may all be formed of similar or different materials.

FIG. 1 shows only an exemplary embodiment of the present disclosure, wherein a stitching configuration 100 includes a central strand 50 having enlarged portions 55 that have a generally trapezoidal shape and extend at approximately regular intervals along the length of the central strand 50. The enlarged portions 55 may extend along the entire length of the inner strands 50 or only a portion of the length of the inner strands 50. The outer suture 10 is a coreless suture (coreless strand) covering the central strand 50 and the enlarged portion 55. The outer suture 10 is a coreless suture (coreless strand) that completely covers the central strand 50 with the enlarged portions 55 at least in the transverse direction, i.e. the outer surface of each enlarged portion 55 is completely covered by the outer suture 10. Preferably, the outer seam 10 covers the center strand 50 with the enlarged portion 55 in both directions (i.e., in the longitudinal and transverse directions). The center strand 50 with the enlarged portion 55 may be disposed within the interior space/volume of the coreless suture 10 (e.g., by insertion into the coreless suture 10) to form the suture configuration 100 (the coreless suture 10 is no longer coreless after the insertion step). Once the inner strands 50 with the enlarged portions 55 are disposed within the outer strands 10, the outer strands 10 will acquire a "bumpy" feel as the enlarged portions will apply pressure along the inner surfaces of the outer strands 10, but will not penetrate the outer surfaces of the outer strands 10.

Fig. 2 and 3 show suture configurations 200, 300 having enlarged portions 155, 255 similar to the enlarged portions 55 of fig. 1, where they are also spaced apart along the length of the suture 50 and completely covered by the outer sheath 10, but differ in the shape of the enlarged portions. For example, enlarged portion 155 is in the form of a bead or spherical structure, while enlarged portion 255 is in the form of a teardrop structure. The enlarged portions 255 are "spinous processes" fixed at defined intervals along the inner strand 50, similar to bathroom drain chains. The spinous process can be asymmetric with the tapered end toward the band (as described in detail below). After the working distance length is properly defined, the suture will be aligned with cored #2Same and then tapering to a smaller 2.0To facilitate loading in the strapping mechanism and to form a knotless seam construction having a joint and a joint forming mechanism. Once the suture is passed through the soft tissue, the tail (tapered end) is passed through the aperture/opening at the distal end by shuttling it through the aperture/openingAnd (4) a mouth. The suture is then pulled through until it is fully cinched. When it is tightened, the thicker protuberance engages the aperture/opening and locks the suture under tension, preventing the suture from moving in any direction.

Fig. 4-7 illustrate a suture configuration 400 having an enlarged portion 355 in the form of a knot 355 extending along the central strand 50 (fig. 4). The inner core 50 shown in fig. 4 is a smaller suture provided with a knot 355. A coreless suture or wrapping envelope 10 (outer strand 10) covers the inner core 50. The outer strand 10 completely covers the inner center strand 50 with the knot 355 to form the stitched construction 400 shown in FIG. 5.

The securing/interference of the enlarged portion may be accomplished in various ways and with various locking structures. For example, and as shown in fig. 5-7, the exemplary stitch construction 400 is provided with a loop 11 for forming the rail clip 166. Knot 355 (knot hump 355) provides a ratcheting point to prevent the rail hanger sleeve from slipping off. Fig. 7 shows a schematic view of the final restoration with a suture construct 400 having an enlargement 355 that is locked in place by the rail clip 166, i.e., cannot slip or slide out of the loop formed around the first tissue 90 (e.g., soft tissue 90) attached to the second tissue 80 (e.g., bone 80).

The loop 11 may be formed integrally with the suture construct or separate from the suture construct. The loop 11 may be part of the outer strand 10 or alternatively part of the inner strand 50. In a further embodiment, the loop 11 may be part of both strands 10, 50. In further embodiments, the loop 11 may be attached to the stitched construction by any method known in the art (e.g., to one or both of the outer and inner strands). For example, fig. 28 shows an exemplary ring 11a attached to an exemplary configuration 100 and further securely attached to a rigid body of a knotless fixation device. In yet another embodiment, the outer strands 10 are spliced into themselves to form a small loop 11 (or double loop) and a joint. The small loop 11 may be integral with the suture strand 10.

The securing/interference of the enlarged portion may be achieved in other ways, for example, in any manner in which the enlarged portion 55, 155, 255, 355 may be locked in, for example, a pre-tied, or slit, or any "eyelet" that provides a tight interference for the enlarged portion.

FIG. 8 shows an exemplary stitched construction 100 through pre-tying 166 of Structure A, which may be part of construction 100, for example, part of an outer strand 10. The pre-ties 166 are interference points for "catching" the enlargement (bump, bead, etc.). The structure A is a rail frame hanging sleeve knot. Structures B and C provide additional points of interference, similar to the pre-tied structure of structure a (where they also "catch" any enlargement/bump/bead passing therethrough), but with a different configuration, namely slit 103 (structure B) or small eyelet 104 (structure C).

Fig. 9-11 illustrate the formation of a closed self-locking ring 99 formed in the configuration of the present disclosure. Fig. 9 is an enlarged view of the loop 11 of fig. 5, which allows the formation of a rail mount hitching knot. The suspension loops are formed by starting with loops 11 prefabricated at the ends of the stitches or by doubling over the single strand. In fig. 10, the tail is threaded through loop 11 to form a "baggage tag" type knot which becomes pre-tied 166 and forms loop 99 a.

Referring now to fig. 11, the tail is passed through a pre-tied rail/strap knot 166. Thereby forming a closed, self-cinching, self-locking loop 99. As described in detail below, the loop may be formed around bone or soft tissue. The tighter the loop is pulled closer to the tissue, the tighter the railtie/drawstring knot around the sutured limb passing through it. This is where the uneven suture passes, but the enlargement/bump prevents the suture from slipping backwards (like a tightening strap). The enlargement/protuberance allows the construct to be "self-locking" and prevents the suture construct from moving in any direction.

Fig. 12-15 illustrate subsequent steps of a method of tissue fixation with the presently disclosed configuration. The suture construct 100 is passed through a first tissue 90 to be attached to a second tissue 80 (e.g., a soft tissue 90 to be attached to a bone 80). Fig. 13 shows a rail/tie knot adjacent to a first tissue 90. The tail 25 passes through a railtie/tie knot to form a closed, adjustable, self-locking, self-cinching, knotless flexible loop 99 around the tissue 90 to be attached to the tissue 80.

Fig. 16 and 17 show another exemplary embodiment of a construction 400 in the form of a flexible strand 10 provided with at least one small closed loop 15 (e.g., two exemplary small closed loops 15) at one end 13 (e.g., the distal end) and a tapered elongate portion/region 25 at the other end 12 (e.g., the proximal end). The enlarged portion 355 is disposed on the enlarged portion (belt segment) 165 of the construction 400, as described in detail above with respect to the previously discussed embodiments. Fig. 17 shows a schematic enlarged view of section a of fig. 16, showing enlarged portion 355 having a particular configuration (i.e., elongated teardrop shape). The enlarged portions 355 are completely covered by the coreless suture strand 10 such that the outer surface of each enlarged portion 355 is completely covered by the inner surface of the strand 10.

The suturing constructions 100, 200, 300, 400 of the present disclosure can also be provided with a shuttle 60, which can be a suture passing instrument, a loader, a shuttle wire, or a passing instrument, such as a FiberLink^TM60 or nitinol ring 60, wherein a closed loop or eyelet 61 is attached to the outer strand 10 of the suture construct.

As shown in fig. 18, the shuttle device 60 is pre-loaded onto the closure ring 11 (threaded through the closure ring 11) of the exemplary suturing configuration 100. In a specific and merely exemplary embodiment, the shuttle device 60 is a suture passing device 60. The shuttle 60 is configured to allow the tapered portion 25 of the outer strand 10 to pass through the eyelet or loop 61 of the shuttle 60 and through the small loop 11 to form a knotless closed adjustable loop 99 having an adjustable length and circumference. The loop 99 is self-locking and self-cinching.

The stitching construction 100 comprises a series of enlargements 55 which may be located at the distal ends 13 of the outer strands 10 on the side close to the loop 11, i.e. on or around the portion 65 (belt segment 5; joint segment 65). The enlargement (ridges and/or barbs and/or ridges and/or knobs) roughens the outer strands 10 (suture 10) for knotless locking. Once the outer strand 10 is threaded through the soft tissue, the tail 25 is passed through the loop 61 by folding and shuttling the tapered end 25 through the loop 11 using the shuttle 60. The flexible strand 10 is then pulled through until it is fully tightened. As it tightens, the thicker enlarged roughness 60 with the enlargement pulls into the loop 11 and prevents the flexible strand 10 from backing out. In this manner, the flexible closed adjustable ring 99 is locked by engagement of the enlarged portion 55 with the inner surface of the ring 11.

In the exemplary embodiment, loop 11 has a very small length and/or circumference to allow tail 25 to pass through the loop and form a closed, knotless, adjustable loop 99. The loop 11 may have a length of about 10 mm. The tapered section/region 25 has a length of about 2-3 inches. The total length of the suture construct may be about 3 to 10 inches, preferably about 5 inches (for an exemplary rotator cuff repair involving the labrum attachment to the glenoid). The loop portion is formed by splicing (in the preferred embodiment), but it may also be formed by other methods known in the art, such as by braiding, weaving, or gluing. The ring 15 may be flexible, foldable, and have a fixed circumference of about 10 mm.

As detailed above, the ring 11 may also be a rail clip ring. The tail 25 is threaded/loaded through the small loop 11 of the flexible strand 10, as shown for example in figure 3. The tail is pulled through until a small opening is left (fig. 4). A suture loader 60 is added to pull the tail through the rail mount pocket after the tail is passed through the tissue.

In an exemplary embodiment, the flexible strands 10 of the suture constructs 100, 200, 300, 400 are sutures formed primarily of a braid, such asA CL braid, which is a coreless braid having Ultra High Molecular Weight Polyethylene (UHMWPE). In another exemplary embodiment, the outer strands 10 are sutures formed primarily of polyester or similar material. For example, the outer strand 10 may be formed from polyester yarn (twisted yarn of polyester) or a polyester suture in the form of a coreless braid or sheath, which may be of multifilament, braided, knitted or woven polyester construction, with the polyester provided alone or in combination with any other known suture material. In the exemplary embodiment only, the outer strands 10 are braided coreless suture with about 100% polyester.

For example, at least one or all of the suture sections of the exemplary suture constructs 100, 200, 300, 400 may be coated with (partially or fully) wax (beeswax, petroleum wax, polyethylene wax, or otherwise), silicone (Dow Corning silicone fluid 202A or otherwise), silicone rubber (Nusil Med 2245, Nusil Med 2174 with an adhesion catalyst, or otherwise), PTFE (Teflon, Hostaflon, or otherwise), PBA (polybutyrate), ethyl cellulose (fillodel), or other coatings to improve lubricity, knot safety, softness, operability, or abrasion resistance of the final suture construct.

The elongate tapered region 25 of the surgical configuration of the present disclosure allows the flexible strands/sutures to be pushed through small and very small diameter tubes and sleeves (e.g., such as lasso instruments), but with a fixation device (such as, for example, a snare wire instrument)Knotless suture anchors such as (push-lock) anchors) are firmly fixed.

The surgical stapling constructs 100, 200, 300, 400 can have a cross-section of various forms and geometries, including, inter alia, circular, oval, rectangular, or flat, etc., or combinations of these forms and geometries. The diameter of the formations 100, 200, 300, 400 may be constant or may vary. Tapered region 25 may include a plurality of adjacent tapered regions, each region having a diameter different from the diameter of an adjacent region. In only an exemplary embodiment, the region 25 may include three adjacent regions, each region having a different taper than the adjacent regions.

At least a portion of the fibers of the suture constructs 100, 200, 300, 400 may comprise strands of high strength suture material, such as Arthrex disclosed in U.S. Pat. No.6,716,234Sutures, the disclosure of which is incorporated herein by reference in its entirety, have optional colored strands to help surgeons distinguish between various suture lengths.

The surgical stapling configurations 100, 200, 300, 400 (by themselves or in any combination) are suitable for use in stapling applications, which may be used in surgical procedures, such as rotator cuff repair, achilles tendon repair, patellar tendon repairReconstructive, ACL/PCL reconstruction, hip and shoulder reconstruction surgery, and in suture applications for or with suture anchors. In exemplary embodiments only, the suture constructs 100, 200, 300, 400 may be used in suture applications that do not involve tying knots, e.g., in connection with suture anchors (e.g.,and/orSuture anchors) or for knotless arthroscopic suture repair (e.g., knotless one-way rotator cuff repair, or SpeedBridge using knotless and suture-only threading procedures^TMRepair), etc., but the suture application has simplified steps as no nitinol wire or similar structure is required.

In merely exemplary embodiments, one or more configurations 100, 200, 300, 400 are employed to join a first tissue portion (e.g., a first soft tissue) with a second tissue portion (e.g., a second soft tissue) in a side-to-side closure repair. The construct is first passed through a first tissue portion. The tail (tapered region 25) is passed through or around the second tissue portion and then through the locking structure/mechanism/device (e.g., loop, eyelet, slit, or combination thereof) with a shuttle device (loader) by folding and shuttling the tapered end 25 through the locking structure. The flexible strand 10 (suture 10) is then pulled until it tightens and achieves the desired tension on the closed adjustable loop 55. As the flexible strand 10 tightens, the enlarged portion 65, 165 (thicker) of the construction 100, 200, 300, 400 pulls into the locking mechanism (loop 11, 15, 166, 103, 104) and locks the enlarged portion 55, 155, 255, 355 to the inner surface of the loop 11, 15, 166, 103, 104 (to the flexible strand 10) to prevent the outer strand 10 from backing out. In an exemplary embodiment, the enlargement is a plurality of ridges/barbs/nubs that engage and lock the suture 10 under tension. The outer strands may be standard braided sutures which are tapered and have three different widths throughout their length. The outer strands may be flexible. The outer strand 10 may be flexible before and after the inner core 50 with the enlarged portions 55, 155, 255, 355 is disposed within the outer strand 10. The inner strands 50 may be rigid or flexible.

Fig. 19 shows a schematic view of a surgical site undergoing a method of securing soft tissue to bone (or soft tissue to soft tissue) according to a method of the present disclosure. In an exemplary embodiment only, the surgical site is the shoulder and the tissue is the labrum 90 to be attached to the glenoid 80 with the exemplary surgical construct 100. Although the following embodiments will be described with reference to the exemplary configuration 100 for simplicity, the present disclosure has applicability to any of the surgical configurations 100, 200, 300, 400 (used alone or in any number, and also in any combination thereof).

Securing soft tissue to bone (such as securing the labrum to the glenoid) typically involves making an incision to access the surgical site and then reattaching the soft tissue. When soft tissue is attached to bone, the surgeon drills a cavity in the bone and inserts a fixation device (such as a bone anchor). Typically, bone anchors are formed of metal, composite materials, plastic or bioabsorbable materials and are held in place by threads or barbs. If an anchor is used, the anchor typically includes an eyelet through which the structure 100 is then threaded.

After forming the band suture (fig. 19) and locking the configuration with enlarged portions 55, 155, 255, 355 of the inner surface region of the penetrating ring 11, the suture construct 100 may be secured into the bone 80 with one or more securing devices, such as one or more suture anchors like anchor 70 of fig. 19, by passing the tapered end region 25 through the eyelet of the anchor (not shown) and then securing the knotless securing device 70 into the bone with the suture construct 100, thereby obtaining a final repair 600 (fig. 19).

The flexible strands may also be secured by using any number of knotless or other securing devices, such as two securing devices, for example two knotless securing devices 70 having two eyelets (instead of one securing device). This technique can be repeated multiple times at different locations in the bone (i.e., multiple band sutures are made at different locations around the labrum).

A method of securing a first tissue to a second tissue with a suture construct 100, 200, 300, 400, comprising, inter alia, the steps of: (i) passing or surrounding a first tissue with a suture construct 100, 200, 300, 400 comprising an outer strand 10 housing an inner strand 50 having a plurality of enlargements 55, 155, 255, 355; and (ii) locking the suture configuration by forming a band around the tissue and locking the at least one enlarged portion 55, 155, 255, 355 to the inner surface of the locking structure 11, 15, 166, 103, 104. The method may further comprise the steps of: (iii) attaching the suture construct 100, 200, 300, 400 to the knotless fixation device 70; and (iv) placing the knotless fixation device 70 into the second tissue with the attached suture construct 100, 200, 300, 400. The method may further comprise the steps of: (v) the tapered end 25 of the suture construct 100, 200, 300, 400 is threaded through the eyelet of the knotless fixation device. The aperture may be closed (closed opening) or open (i.e., bifurcated opening).

A method of securing a first tissue to a second tissue with a suture construct 100, 200, 300, 400, comprising, inter alia, the steps of: (i) passing or surrounding a first tissue with a suture construct 100, 200, 300, 400 comprising: a length of outer wire strand 10 having a first end and a second end; a locking structure 11, 15, 166, 103, 104 formed at the first end; a tapered region 25 formed at the second end; a joint/enlarged region 65, 165 located near the first end and the locking structure 11, 15, 166, 103, 104, wherein the enlarged region (or the region adjacent to the locking structure 11, 15, 166, 103, 104) includes a plurality of enlarged portions that prevent the outer strand 10 from backing out; and a shuttling device 60 having a shuttling ring 61 attached to the outer strand 10; (ii) passing the tapered ends 25 of the flexible strands through the shuttling ring 61; and (iii) pulling the shuttle device to allow the flexible strands to form a cinch ring 99 around the tissue 80, 90 and lock the enlarged portions 55, 155, 255, 355 to the inner surface of the locking structure 11, 15, 166, 103, 104. The method may further comprise the steps of: (iv) attaching the suture construct 100, 200, 300, 400 to the knotless fixation device 70 by threading the tapered end 25 of the suture construct 100, 200, 300, 400 through the eyelet of the knotless fixation device; and (v) placing the knotless fixation device 70 into the second tissue with the attached suture construct 100, 200, 300, 400.

Suture constructs 100, 200, 300, 400 may be used in surgical procedures such as rotator cuff repair, achilles tendon repair, patellar tendon repair, and the like. Although the present invention has been described with reference to a particular application (i.e., securing the labrum to the glenoid in a shoulder repair), it must be understood that the suture configuration of the present invention is applicable to any type of repair (any repair other than a shoulder repair), and therefore, the present invention is not limited to such merely exemplary embodiments.

In an exemplary embodiment only, the fixation device 70 is a knotless suture anchor, such as the two-piece Arthrex disclosed in US 7,329,272Anchors, or Arthrex disclosed in US8,012,174, granted on 6/9/2011, US 9,005,246, granted on 14/4/2015, and US 2013/0296936, published on 11/7/2013Anchors, the disclosures of all of which are incorporated herein by reference in their entirety.

The suture constructs 100, 200, 300, 400 may also be used with a knotted fixation device, such as a knotted anchor. Accordingly, the present disclosure is not limited to the use of the suture constructs 100, 200, 300, 400 with knotless fixation devices, such as the fixation device 70, and the present disclosure contemplates the use of the suture constructs 100, 200, 300, 400 with any type of fixation device (knotless or knotted, or a combination of knotless and knotted fixation devices). Exemplary configurations of the present disclosure may be used in various tissue repair, such as using SpeedBridge^TMAnd SpeedFix^TMKnotless rotator cuff repair with repair techniques or similar soft tissue and bone reattachment techniques in arthroscopic rotator cuff repair (using knotless fixation devices to form single, double or multiple row configurations), orDemanding applications such as AC joint reconstruction and other areas where tissue traction may be considered.

The strands 10, 50 may be made of any known suture construction, such as multifilament, braided, knitted, woven suture, or fibers comprising Ultra High Molecular Weight Polyethylene (UHMWPE)Sutures (disclosed in US 6,716,234, the disclosure of which is incorporated herein by reference in its entirety).The suture is formed from an advanced high strength fibrous material, namely Ultra High Molecular Weight Polyethylene (UHMWPE), available under the trade names spectra (honeywell) and dyneema (dsm), which is braided with at least one other natural or synthetic fiber to form a length of suture material. It is preferable thatThe suture includes a core within a hollow braided construct, the core being a twisted yarn of UHMWPE. The strands 10, 50 may also be formed by sewing tapes, such as ArthrexThis is a high strength suture tape which is woven and rectangular in cross-section and is disclosed in US 7,892,256, the disclosure of which is incorporated herein by reference in its entirety. The surgical constructs 100, 200, 300, 400 may be used with any type of flexible material or suture known in the art.

The strands may also be formed of a rigid material or a combination of rigid and flexible materials, depending on the intended application. The strands may also be painted and/or provided in different colors. The strands may also be provided with coloured tracer strands or be provided to be otherwise visually contrasting with the rest of the element of the construction, for example this may be a plain colour, a solid colour or show a different tracer pattern. The various structural elements of the surgical constructs 100, 200, 300, 400 may be visually coded, making identification and handling of the suture legs simpler. Easy identification of sutures is particularly advantageous in surgery, particularly during arthroscopic (e.g., endoscopic and laparoscopic) surgery.

The surgical constructs 100, 200, 300, 400 may comprise surgical sutures or similar materials, for example, surgical sutures or similar materials may be coated with (partially or completely) wax (beeswax, petroleum wax, polyethylene wax, or otherwise), silicone (Dow Corning silicone fluid 202A or otherwise), silicone rubber (Nusil Med 2245, Nusil Med 2174 with an adhesion catalyst, or otherwise), PTFE (Teflon, Hostaflon, or otherwise), PBA (polybutyrate), ethylcellulose (fillodel), or other coatings to improve the lubricity, knot safety, softness, maneuverability, or abrasion resistance of the suture or tape.

Preferably, the elongated tapered end 25 may have a very fine end, for example, coated, impregnated, or hardened with a material such as plastic.

The disclosed suture configuration has a central strand of cored suture with fixed "spinous processes" at defined intervals, similar to bathroom drain chains. Preferably, the spinous process/enlargement is asymmetric with the tapered end facing the band. After the working distance length is properly defined, the suture will be aligned with the coredSame and then tapered to smallerTo facilitate loading into the strap mechanism.

The suture constructs 100, 200, 300, 400 of the present disclosure discussed above may be used alone, as described above, and may also be used with various soft and/or hard anchor devices to form the suture anchor assemblies 111, 112, 113, 114, 115, 116, 117 described in detail below.

For example, fig. 20 shows a suture anchor assembly 111 having a fixation device or anchor 71 and an exemplary suture configuration 100 coupled to an anchor body by a locking ring 100 a. The locking ring 100a is located on top of the anchor 71 but is secured to the anchor body by, for example, a static knot 72.

Fig. 21 illustrates a suture anchor assembly 112 including a fixation device or anchor 71 and an exemplary suture configuration 100 coupled to an anchor body. The suture construct 100 extends within the body of the anchor 71 and around a post 73 or similar structure located at the distal end of the anchor body. As the rugged suture 100 is pulled in (by pulling in a cinching direction such as the direction of arrow "a 1" (fig. 21)), the rugged suture is locked in/within the anchor body. Anchor 71 may be pre-placed into a bone hole or opening.

Fig. 22 illustrates a suture anchor assembly 113 that includes a fixation device 75 in the form of a button 75 and an exemplary suture configuration 100 coupled to the button 75. Button 75 is shown as having two through holes or apertures 75a which, together with enlarged portion 55 of formation 100, can securely lock suture formation 100; however, the present disclosure contemplates any device/button having any shape/configuration (i.e., oval, circular, elliptical, S-shaped button, etc.) and having any number of openings/apertures that may receive at least a portion of exemplary configuration 100.

Fig. 23 illustrates an example suture configuration 100 coupled to a knotless anchor to form an example suture anchor assembly 114. The rugged suture (suture construct) 100 is captured within the body of the knotless anchor as part of the knotless anchor. The suture construct 100 is securely fixed to the anchor body by a static knot 72 and forms a loop 290a and a joint 65 within the body of the anchor. The joint may be formed by employing a shuttle such as the shuttle 60 having the loop 61 discussed above. Ring 290a may be a closed, flexible, knotless adjustable ring having an adjustable circumference and located partially within the body of anchor 71. The connector 65 may be entirely located within the body of the anchor 71. The suture construct 100 may be looped around a post 73 (or similar structure) located at the distal end of the knotless anchor body.

The suture anchor assembly 115 (fig. 24) includes an exemplary suture configuration 100 between the anchor body 71 and the bone (i.e., on the outer surface of the anchor) to provide enhanced tissue fixation.

Fig. 25 and 26 illustrate exemplary suture anchor assemblies 111 and 114, respectively, for attaching a first tissue 90 to a second tissue 80, such as attaching a soft tissue 90 to a bone 80. The suture anchor assemblies 111, 112, 113, 114, 115 of the present disclosure provide simplified tissue repair while ensuring reliable fixation of a first tissue to a second tissue.

An exemplary suture anchor assembly 111 formed from an anchor 71 preloaded with a suture construct 100 (rugged suture 100) is installed in a predrilled hole/socket/opening 82 formed in the bone 80. Insertion of anchor 71 into bone preferably forms a tight fit to anchor suture construct 100 therein. Once the suture anchor assembly 111 is installed into the bone hole 82, the tissue securing end 100b of the suture construct 100 remains outside of the bone hole 82. The tissue securing end 100b is passed through the soft tissue 90 and the loop 100a, and then pulled away from the bone 80 in a tightening direction a1 (fig. 25), allowing the enlargements 55, 155, 255, 355 to lock the device in place and prevent the strands 10/50 of the suture construct 100 from moving in the opposite direction (i.e., in a loosening direction), and forming the final restoration 190.

Fig. 26 illustrates the final repair 290 with the suture anchor assembly 114 installed into the bone hole 82 with the tissue securing end 100b of the suture construct 100 retained outside of the bone hole 82 and forming a closed, knotless, flexible adjustable loop 290a around the tissue 90. Closed, knotless adjustable loop 290a is locked in place by enlargements 55, 155, 255, 355 which prevent the suture ends from moving in the opposite direction to a1 (i.e., in the direction opposite to tightening direction a 1).

The suture constructs 100, 200, 300, 400 of the present disclosure described above may be used alone and/or with anchors having hard bodies (as described above), and may also be used with soft anchors to form the exemplary soft anchor assembly 116 described in detail below with reference to fig. 27.

Fig. 27 shows the soft suture anchor 40 pre-loaded with the suture construct 100. The soft suture anchor 40 is a soft anchor that may include a tubular sheath, such as disclosed in Dreyfuss et al, U.S. patent No.9,463,011, the entire disclosure of which is incorporated herein by reference in its entirety. The tubular sheath 40 may be formed of a flexible material such as suture or polyester, and may be of woven, braided or knitted construction, and/or may be formed of yarn, fiber, silk, suture, braid or the like, or combinations thereof. The tubular sheath 40 has two opposite open ends through which the suture construct 100 exits. One or both ends of the suture construct 100 may be coupled to various structures, such as a shuttle device, another fixation device, a ring, etc., to allow the ends to pass through and/or around soft tissue and secure the soft tissue to bone.

As detailed in Dreyfuss et al, U.S. patent No.9,463,011, a tubular sheath pre-loaded with a suture construct 100 is inserted and secured into a bone, for example, by being inserted and secured into a predrilled hole/socket/opening formed in the bone, such that the tubular sheath bunches within the bone hole and is thereby securely fixed in place in the bone hole. To facilitate insertion and installation of the tubular sheath 40 into bone, an inserter having a bifurcated tip and/or mallet tool may be used.

Once the tubular sheath 40 is inserted into the bone hole, at least one end of the suture construct 100 passes through/around the soft tissue to allow a closed, knotless, flexible adjustable loop to be formed around the soft tissue 90 and to allow engagement of the enlarged portions 55, 155, 255, 355 to lock the device in place and prevent movement of the strands 10/50 of the construct 100 in the opposite direction (i.e., in the unthreading direction). The enlargements 55, 155, 255, 355 may also engage the tubular sheath 40 to lock the final restoration in place to ensure attachment of soft tissue to bone. The enlarged dimension of the enlarged portions 55, 155, 255, 355 relative to the strand 10/50 prevents the final repair from loosening.

Fig. 28 illustrates yet another exemplary suture anchor assembly 117 of the present disclosure. As in the previous embodiments, and for simplicity, the suture anchor assembly 117 is explained with reference to the exemplary configuration 100; however, the present disclosure may be applied to any of the configurations 100, 200, 300, 400 in any combination and/or by itself and/or with other additional securing devices. As described in detail below, the exemplary anchor assembly 117 includes one or more rugged sutures loaded into a pre-placed anchor, then internally tensioned and secured with a spline insert.

The suture anchor assembly 117 of fig. 28 includes a fixation device or anchor 71a and an exemplary suture configuration 100 coupled to the anchor body by a loop 11 a. The loop 11a is located within the body of the anchor 71a and at the distal end of the body of the anchor 71 a. The loop 11a may be insert molded within the anchor body and/or may be secured to the anchor body by, for example, a static knot 72 a.

The exemplary suture configuration 100 is coupled to an anchor body of the device 71 a. The suture construct 100 extends within the body of the anchor 71a and through the loop 11a at the distal end of the anchor body. As shown in fig. 28, the rugged suture 100 passes through the loop 11a and extends along the first and second longitudinal channels 74a and 74a located within the anchor body and communicating with each other. The diameter D1 of the first passage 74 is greater than the diameter D2 of the second passage 74 a. The first and second passages 74, 74a may extend along a longitudinal axis of the anchor body of the anchor 71, and may optionally be concentrically positioned relative to each other.

Suture construct 100 of assembly 117 may alternatively and additionally be secured with a locking element, such as insert 73 provided with a plurality of arms/legs/prongs 73a extending from threaded body 73 b. The body 73b of the insert 73 is designed to matingly engage the distal-most threaded end of the driver 76. Inserter 73 is deployable within the anchor body of anchor 71. For example, the insert 73 may be provided with a deployable or extendable arm/leg/bifurcation 73a which, in a first position, is in a first, undeployed or closed state, and, in a second position, is in a second, deployed or open state.

In the merely exemplary embodiment, the insert 73 is provided with an arm/leg/fork 73a which, in a first position and when inserted through the second passage 74a, is in a first state (not deployed or closed) and which, in a second position and when inserted in the first passage 74, is in a second state (deployed or open). When in the deployed position, the arms/legs/prongs 73a are fully located within the first channel 74 and exert lateral pressure on the longitudinal interior walls of the first channel 74 and on the portion of the rugged suture 100 located within the first channel 74. The body 73b of the insert 73 has an outer diameter approximately equal to the diameter D2 of the second passage 74 a. When in the deployed state, the maximum outer diameter of arm/leg/bifurcation 73a is approximately equal to diameter D1 of first passage 74. In this way, the inserter 73 secures and locks the suture construct 100 in place internally, i.e. the rugged suture is locked in/within the anchor body. Enlarged portions 55, 155, 255, 355 are locked in place by insert 73 (i.e., between the inner wall of first passage 74 and arms/legs/prongs 73a of insert 73) and prevent release of the final repair. Anchor 71 may be pre-placed into a bone hole or opening. In this exemplary embodiment, suture construct 100 is secured and secured/locked to anchor 71 by loop 11a and inserter 73.

The term "high strength suture" is defined as any elongated flexible member, the choice of materials and dimensions depending on the particular application. For illustrative but non-limiting purposes, the term "suture" as used herein may be a string, wire, thread, wire, fabric, or any other flexible member suitable for tissue fixation in the body.
