Tissue repair fabric
First Claim
1. A prosthesis comprising two or more superimposed, bonded layers of collagenous tissue material,(a) wherein the layers of collagenous tissue material are sourced from a mammalian source and is the tunica submucosa of the small intestine, fascia lata, dura mater, or pericardium(b) wherein the layers are bonded together by heat welding from about 50°
- C. to about 75°
C.,(c) wherein said prosthesis is crosslinked with a crosslinking agent that permits bioremodeling, and,(d) wherein said prosthesis is sterilized with peracetic acid, which, when implanted into a mammalian patient, the prosthesis undergoes controlled biodegradation occurring with adequate replacement by the patient'"'"'s living cells such that the implanted prosthesis is remodeled by the living cells.

Abstract
This invention is directed to prosthesis, which, when implanted into a mammalian patient, serve as a functioning replacement for a body part, or tissue structure, and will undergo controlled biodegradation occurring concomitantly with bioremodeling by the patient'"'"'s living cells. The prosthesis of this invention, in its various embodiments, thus has dual properties. First, it functions as a substitute body part, and second, it functions as bioremodeling template for the ingrowth of host cells.
