Self adhering implantable mesh prosthesis with reduced insertion profile
First Claim
1. A method of implanting a self-adhering mesh prosthesis for repairing animal tissue, the method comprising:
- providing a sheet of mesh material comprising first and second opposing major surfaces and adhesive disposed on a plurality of portions of at least the first major surface of the sheet, the plurality of portions comprising less than a whole of the first major surface;
folding the sheet for passage through a restricted passageway into an animal body, the sheet passing through the passageway in a longitudinal direction of the passageway, the folding being conducted so as to cause folded portions of the sheet to abut one another, and to minimize overlap of the portions that bear adhesive with each other in the transverse plane, to provide a compacted mesh prosthesis having a low-profile shape for passage through the passageway;
passing the compacted mesh prosthesis through the passageway;
unfolding the sheet after passage through the passageway; and
adhering the sheet to tissue in the animal body using the adhesive that was disposed on the sheet prior to passing of the sheet through the passageway into the animal body.

Abstract
The present invention is an implantable adhesive mesh prosthesis for reinforcing and/or repairing a defect in tissue that is easy to roll into a small diameter cylinder or other low-profile shape for passing through a trocar, incision, or other surgical instrument. More specifically, the adhesive may be applied to the mesh material in a pattern that leaves a significant portion of the surface area of the mesh material free of adhesive. In one embodiment, the adhesive is applied only near the outer perimeter of the mesh product. In another embodiment, the adhesive is applied in spots over all or a portion the surface of the mesh product. In yet another embodiment, the adhesive is applied in parallel lines on the surface of the mesh product and the mesh may be rolled up around an axis parallel to the lines of adhesive.
