Technical Field
The present disclosure relates generally to mesh coverings for implants, and more particularly, to mesh bags for implants and methods of use thereof.
Background
The present disclosure relates to the field of surgical implant devices. Aspects of the present disclosure are particularly directed to the use of bioabsorbable, flexible mesh bags to support and stabilize a mammary prosthesis.
Synthetic implants composed of silicone or saline are commonly used for breast augmentation and breast reconstruction, but in both cases the soft tissue envelope alone is sometimes insufficient to hold the implant in place. Furthermore, in many cases, when using circular implants, it is difficult to obtain or maintain an anatomically suitable breast shape. Because of these deficiencies in natural tissue, revision surgery is sometimes required to remodel, reposition, lift, or otherwise modify the implant and/or tissue surrounding the prosthesis. Revision surgery can be avoided if additional, shaped, locally positioned support structures are provided for the breast implant. Internal brassieres, sometimes using a sling or hammock structure, provide additional support for the breast implant. Common materials for internal bra hammocks are surgical mesh and acellular tissue.
These internal brassieres provide additional support to the breast implant, but there is still a need for improved support and stability to ensure long lasting results in breast augmentation and reconstructive surgery.

Detailed Description
The present disclosure generally relates to mesh bags for securing an implant to the body of a patient. According to various embodiments, a mesh bag includes a mesh wall defining an enclosure having an opening. The mesh bag also includes a drawstring configured to close the opening when pulled out to prevent the surgical implant from exiting the housing. The mesh bag may also include a mesh tab extending from the mesh wall that provides a surface for suturing the mesh bag to an interior surface of a patient's body. The mesh bag may further include strands extending from the mesh wall and needles attached to the ends of the strands. The strands can be configured to secure the mesh wall around the surgical implant when pulled.
The mesh bags disclosed herein provide additional support and stability. After inserting the implant into the mesh pocket and suturing the tag to the chest wall, the 360 degree mesh shell can localize the implant and reduce the weight of the surrounding soft tissue during the healing process. The latter benefit is particularly advantageous in post-mastectomy breast reconstruction, which is often performed in situations where the blood supply to the remaining skin flap is inadequate. The tabs on the outer wall of the mesh pouch provide additional surface area to suture and support the wrapped breast implant without the risk of puncturing the implant by suturing directly through the outer wall of the pouch. In contrast to the hammock method, which provides support and positioning only in the cranio-caudal plane, the mesh bag method described herein can fully bear the weight of the implant, force the implant into the desired shape, and position the implant on the medial and lateral sides. Furthermore, for a given implant and soft tissue defect, it is less time consuming to place the implant in a pre-formed bag, tighten it and sew a small number of labels, than to cut a custom hammock or sling from a flat plate and then cut it out to place it in an appropriately sized and shaped half pocket.
Various embodiments of mesh bags include one or more straps around the opening that can be pulled to close the opening. The walls of the mesh bag can be flush with the implant using a strap design. This design helps to eliminate material build-up and the resulting air pockets that can lead to bacterial infection and swelling.
Embodiments of mesh pouches described herein do not have an absorbable coating. Rather, the embodiments described herein are constructed entirely of bioabsorbable materials. The entire device is made of bioabsorbable materials, which can reduce the complications and infections common to non-bioabsorbable mesh implants.
The various embodiments described herein provide a long lasting effect of breast augmentation or reconstruction for the patient, thereby reducing the need for subsequent revision surgery.
