Abstract

Abstract A bovine bioprosthetic heart valve comprising a stent 1 made of a biocompetent and fatigue resistance material, said stent comprising a waist 1a and three spaced apart prongs 16 projecting therefrom, said waist having three curvatures vertically consecutively and said prongs being at the mounts formed at the junctions of said curvatures, said stent being covered with a biocompetent and durable polymer cloth (1d) stitched thereto, and three leaflets 3 of bovine pericardium mechanically cleaned and shaped and treated with anticalcific solution and preserved in a preservative solution, said leaflets each being disposed on the outer surface of said stent between adjacent prongs and stitched (1e) to the waist and prongs, and a sewing ring (4) of a biocompetent and durable polymer cloth located over said waist and stitched thereto. <IMAGE>
