ABSTRACT:
A prosthesis and method are disclosed for patching openings in body membranes such as the dura mater. The novel prosthesis includes patch comprising a patch flange and a suture flange extending circumferentially around the patch. The patch is implanted inside the membrane such that the patch completely covers the opening to be closed. The lip of the opening laps the suture flange and is secured by sewing sutures through the suture flange and the lip, but not through the patch. Accordingly, the tissue underlying the patch is shielded from the suture threads and perforations by the patch flange. The patch is of lubricious and biologically inert materials that is effectively nonadhesive to scar growth which forms on healing wounds. Thus, the novel prosthesis reduces the potential for adhesion between the underlying tissues and the membrane due to scar formation following surgery, particularly surgery on the central nervous system.
