Hernia patch

摘要

A hernia patch supporting tissue in-growth conforms to a tissue wall upon surgical installation and fixation within a patient. The hernia patch can include a base and positioning straps. The base is formed of two layers that are affixed to each other around the perimeter of the patch, for example by stitching. A stabilizing washer is provided between the two layers, and the stitch is provided peripherally around the stabilizing washer, keeping the washer free-floating between the layers. The base, positioning straps, and stabilizing washer are formed of a structure that does not separate the layers of the implant or form a space in the form of a pocket, and promotes more uniform and confluent tissue incorporation or in-growth after implantation. The hernia patch may further include a hydrolysable bioabsorbable cross-linked coating of a fatty acid based material, such as an omega-3 fatty acid based material.

主权项

1. A patch for treating a hernia, comprising:
a base comprising two mesh layers and a tissue conformable, flat circular stabilizing washer disposed within a continuous interior compartment between the two mesh layers, the continuous interior compartment extending continuously from an outer periphery of the stabilizing washer to a center of the base, wherein the two mesh layers are only affixed to each other at a location between the outer periphery of the stabilizing washer and an outer periphery of the base and perimetrically exterior to the stabilizing washer in such a way as to form the continuous interior compartment with the stabilizing washer free floating therein; and a positioning strap attached to the base in such a way that when a pull force is applied thereto during implantation, the base is pulled by the positioning strap toward a tissue location, and the base is configured to conform against the tissue location.
