Implantable prosthesis
First Claim
1. An implantable prosthesis for occluding the opening of a muscle or tissue defect, comprising:
- a flexible, generally flat patch of implantable material including a body portion constructed and arranged to cover the defect opening when positioned thereagainst; and
a plurality of barbs disposed on said patch of implantable material and extending at spaced locations from said patch of implantable material, wherein said plurality of spaced barbs prevent migration of said implantable prosthesis after implantation.

Abstract
An implantable prosthesis for occluding the opening of a muscle or tissue defect. The implant is laparoscopically deliverable with a system for loading and delivering the prosthesis through a trocar cannula. The prosthesis includes an implantable material with a body portion sufficient to extend across and occlude a defect opening. Antimigration barbs extend from the implantable material to prevent migration of the prosthesis after implantation. A semi-rigid ring may be attached to the material for supporting the body portion. The barbs may be located on the ring. The implantable prosthesis may be provided with a sufficient hoop strength to prevent the body portion from collapsing into the defect opening.
