Technical Field

The invention relates to the field of medical instruments, in particular to a loading tool, a loading system and a loading method for an implant.

Background

Interventional therapy is a new treatment mode which integrates image diagnosis and clinical treatment into a whole and is developed in recent years. Under the guidance and monitoring of digital subtraction angiography, CT (computed tomography), ultrasound, magnetic resonance and other imaging devices, a puncture needle, a catheter and other interventional devices are used to introduce a specific instrument implant into a diseased region of a human body through a natural duct or a tiny wound of the human body for treatment. Has the advantages of accuracy, safety, high efficiency, wide application range, less complications and the like, and is the first choice treatment method for some diseases.

Vascular interventional techniques are one type of interventional therapy, and in short, use the blood vessels of the human body as a natural pathway to deliver an implant to a diseased cardiovascular site for treatment. The most intuitive characteristic of the method is that the implanted object is large in size, in particular to an interventional heart prosthesis valve, an interventional occluder and the like. This technique requires the implant to be compressed to a small diameter for loading into the transporter conduit. The implant or biological tissues and polymer materials attached to the implant are easily damaged by over-extrusion, uneven compression or local accidental twisting and bending, which finally results in defective function and reduced service life of the implant, even failure of normal implantation.

In addition, the implant itself may be difficult to compress in order to meet the requirements of treatment, lesion structure, design, materials, etc. Existing loading tools are only suitable for compressing relatively small volume implants (e.g., conventional aortic valve prosthetic valves) with a small ratio of radial dimension to axial length.

For implants with large volume or large ratio of radial dimension to axial length, such as mitral valve prosthesis valve, tricuspid valve prosthesis valve, etc., when the existing loading tool is used for compression loading, the prosthesis valve is easy to be seriously twisted, deformed, uneven, etc. Meanwhile, for some implants with large radial supporting force, normal compression cannot be performed by the existing loading tool at all. Taking mitral prosthetic valve as an example: due to the anatomically large annulus size of the native mitral valve of the heart, the support structure (i.e., stent) implanted in the prosthetic valve of the mitral valve to carry the prosthetic leaflets needs to be radially large in size to conform to the native mitral valve annulus and leaflets of the heart for anchoring and sealing purposes. Anatomically, the aortic valve is adjacent to the mitral valve, so an axially oversized mitral prosthetic valve can impede the ejection function of the aortic valve, resulting in the creation of left ventricular outflow tract occlusions. Based on the above two points, the radial dimension of the mitral valve prosthesis is about 30-80mm, and the ratio of the radial dimension to the axial length is large, usually between 1-3. (the radial dimension of the traditional aortic valve stent is about 15-30mm, and the ratio of the radial dimension to the axial length is about 0.5.) when the existing loading tool is used for loading the mitral valve prosthesis valve, the prosthesis valve is easy to incline and twist in the loading tool due to uneven circumferential stress, and the prosthesis valve is damaged finally. Meanwhile, the support grids of the existing mitral valve prosthesis valve are mostly dense, which causes the circumferential supporting force of the prosthesis valve to be large, and the existing loading tool is extremely difficult to compress the prosthesis valve in place in one step.

Detailed Description

To further clarify the objects, advantages and features of the present invention, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It is to be noted that the drawings are in greatly simplified form and are not to scale, but are merely intended to facilitate and clarify the explanation of the embodiments of the present invention. Further, the structures illustrated in the drawings are often part of actual structures. In particular, the drawings may have different emphasis points and may sometimes be scaled differently.

As used in this specification and the appended claims, the singular forms "a", "an", and "the" include plural referents unless the content clearly dictates otherwise. As used in this specification and the appended claims, the term "or" is generally employed in its sense including "and/or" unless the content clearly dictates otherwise.

The inventors have discovered, as discussed in the background, that implants with larger volumes, implants with larger diametral-axial ratios, and implants with larger radial support forces are highly susceptible to severe distortion, deformation, non-uniformity, etc. when loaded in compression using existing loading tools. And the difficult implants of loading such as jumbo size, big power value or big transverse-longitudinal ratio are compressed and loaded step by step, can effectively solve this kind of implant and easily take place slope, distortion and then lead to the implant to produce the problem of breakage when loading. That is, the implant can be sequentially reduced in size by a plurality of loading tools with different shrinking sizes, and finally the required loading compression size is achieved.

The inventors have also found that the support structures (i.e., stents) of prior art implants that require reduction with a loading tool are often made of shape memory alloys. The shape memory alloy has deformation recovery capability, namely, at low temperature, the shape memory alloy is changed into a martensite phase, shows soft characteristic, can be subjected to operations such as appropriate twisting, bending, compression and the like, and can be recovered to an original form, namely an austenite phase after the temperature is raised. The factors which can cause the phase transformation of the shape memory alloy include temperature and stress, namely, the shape memory alloy can be promoted to be transformed from austenite to martensite by applying certain pressure to the shape memory alloy. The loading tool for the implant provided by the invention utilizes the characteristic that after the stent enters the martensite phase under ice water, the stent is radially compressed and loaded, so that the stent can be effectively compressed to avoid rebounding.

The inventors have further discovered that the stent can be compressed to its final size relatively easily by multiple compression steps resting in ice water.

According to the above idea, the present invention provides a loading tool, a loading system and a loading method for an implant, the loading tool for the implant comprising: a guide cover, a blocking table and at least one compression table; the guide cover is provided with a first inner cavity which is communicated and used for loading the implant, the first inner cavity is provided with a first end part and a second end part which are opposite, and the caliber of the first end part is smaller than that of the second end part; the blocking platform is used for being matched with the guide cover and inserted into the first inner cavity; at least one compression table is provided with a through second inner cavity, the second inner cavity is provided with a third end part and a fourth end part which are opposite, the caliber of the third end part is smaller than that of the fourth end part, and the caliber of the third end part is larger than that of the first end part; wherein: the compression station is configured to compress the implant with the second lumen before the implant is loaded in the first lumen; the block is configured to co-insert into the first lumen after mating with the compressed implant. So dispose, the shrink of first stage can be carried out to the implant to the compression platform, and then the implant cooperates and is spacing with stifled platform, can prevent that the implant from deviating from in the guide cover, and then the implant is worn out and is carried out the shrink of second stage by the first end of guide cover. Therefore, the implant is compressed in stages, so that the method is suitable for the implant with large volume, large radial-axial ratio and large radial supporting force. Preferably, the compression table can be used for plugging the plugging table in the first inner cavity, the compression table is dual-purpose, namely the second inner cavity in the compression table can be used as a reducing hole, the whole compression table can be used as a plugging device for plugging the plugging table, the number of components of loading tools is reduced, the manufacturing cost is reduced, and various problems caused by too many loading tools in the actual loading process are avoided.
