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 the formation of adhesions with tissue and organs, the layer of repair fabric includes a plurality of tissue infiltratable interstices that are constructed and arranged to allow tissue ingrowth thereto, the layer of repair fabric including a first surface and an outer margin with an outer peripheral edge, the outer peripheral edge having a thickness, the outer margin of the layer of repair fabric having been melted and resolidified to substantially eliminate the tissue infiltratable interstices therein and render the entire thickness of the outer peripheral edge of the layer of repair fabric substantially impervious to tissue ingrowth so that the outer peripheral edge is resistant to the formation of adhesions with tissue and organs; and a barrier layer that inhibits tissue ingrowth and the formation of adhesions with tissue and organs thereto, the barrier layer being configured to inhibit the formation of adhesions between at least a portion of the first surface and adjacent tissue and organs.
