Cuffed tubular organic prostheses
First Claim
1. A cuffed tubular organic prosthesis for repairing or replacing tubular organs comprising:
- a flexible tubular body having an inside diameter substantially equal to the inside diameter of an organ to be repaired or replaced; and
a prosthesis cuff on each distal end of said tubular body integral with said tubular body distal ends, each of said prosthesis cuffs having a rounded end for insertion within an open end of the organ and a free end bonded to said tubular body thereby forming a continuous smooth surface extending from the inner surface of the tubular body to the outer surface of the cuff, each of said prosthesis cuffs being adapted to be secured to the end of the tubular organ overlapping each distal end of said tubular body;
said tubular body and each of said prosthesis cuffs together forming a unitary, non-resorbable member adapted to extend permanently between open ends of a tubular organ.

Abstract
A cuffed tubular vascular prosthesis and process for manufacturing the prosthesis are disclosed. A flexible tubular body is formed by coating a glass rod with a polymer solution and air-curing the coating to form a smooth outer surface. The tubular body is removed from the glass rod and turned inside out so that the smooth air cured surface forms the inner wall of the prosthesis. Prosthesis cuffs are formed on the distal ends of the prosthesis by folding the edges of the tubular body back over itself and bonding the turned back edges to the body. The prosthesis is heat set to maintain the cuffs in position during anastomosis. A double cuffed prosthesis is provided by sliding a suture sleeve over the prosthesis cuff, folding the sleeve back over itself and bonding to the prosthesis cuff and the tubular body. The prostheses provide an air-cured non thrombogenetic inner surface to prevent occlusion and efficient separation of the sutures from the lumen of the vessel or tubular organ being repaired to prevent tissue reactivity and thrombosis.

13. A cuffed tubular organic prosthesis for repairing or replacing tubular organs comprising:
-
a flexible tubular body having a smooth air cured inner surface formed by coating a mandrel with a polymer solution, air curing said coating to form a smooth outer surface, removing the mandrel and turning said tubular body inside out so that said air cured smooth surface forms the inner wall of said tubular body, said tubular body having an inside diameter substantially equal to the inside diameter of an organ to be repaired or replaced; and a prosthesis cuff on each distal end of said tubular body, each of said prosthesis cuffs having a continuous smooth air-cured surface extending from the inner surface of the tubular body to the outer surface of the cuff, said cuffs being formed by folding the edges of said tubular body back over said tubular body forming a rounded end for insertion within an open end of said organ and bonding said edges to said tubular body, each of said prosthesis cuffs being adapted to be secured to the end of the tubular organ overlapping each distal end of said tubular body; said tubular body and each of said prosthesis cuffs together forming unitary, non-resorbable member adapted to extend perminantly between open ends of a tubular organ. - View Dependent Claims (15)
