Abstract:
1. An implantable prosthesis for repairing a tissue or muscle wall defect, the implantable prosthesis comprising: a layer of repair fabric that is susceptible to tissue ingrowth and the formation of adhesions with tissue and organs, the layer of repair fabric including a first surface, a second surface opposite the first surface and an outer peripheral edge with a thickness extending from the first surface to the second surface; a barrier layer formed of a material that is substantially free of tissue infiltratable interstices to inhibit tissue ingrowth and the formation of adhesions with tissue and organs thereto, the barrier layer extending across at least a portion of the first surface to inhibit tissue ingrowth and the formation of adhesions between the portion of the first surface and adjacent tissue and organs; and a peripheral barrier formed of a material that is substantially free of tissue infiltratable interstices to inhibit tissue ingrowth and the formation of adhesions with tissue and organs thereto, the peripheral barrier including a section of the barrier layer extending about at least a portion of the outer peripheral edge of the layer of repair fabric and over a portion of the second surface of the layer of repair fabric adjacent the outer peripheral edge, the peripheral barrier being fixedly maintained across the entire thickness of the portion of the outer peripheral edge and the portion of the second surface to inhibit tissue ingrowth and the formation of adhesions between the portion of the outer peripheral edge of the layer of repair fabric and adjacent tissue and organs.
