Heart valve bioprothesis

Claim 1

Heart valve prosthesis with a fixed, integral aortic valve of an adult kangaroo which is positioned in a resiliently flexible, fabric-covered supporting frame having substantially the shape of a cylinder with a substantially circular cross-section and consisting of an axially slightly undulatory annulus comprising three complete waves and of three rounded posts which are positioned at equidistant angles and extend axially from the wave apices and furthermore having a number of perforations, the fabric being shaped as a suture ring near the end face opposite to the posts, the annulus fibrosus, from which the three aortic leaflets originate and in the area of which muscular tissue of the ventricular septum is to be found, extending along the end face of the supporting frame opposite to the posts and being sutured there to the fabric, and the aortic wall or stump, which is cut according to the shape of the supporting frame, being mounted within the annulus and said posts and being sutured to the fabric along the end face of the supporting frame on the side of the posts, in which each of the three leaflets protrude substantially unimpeded from the annulus fibrosus into the aortic lumen, without being coalesced with muscular tissue of the vertricular septum.
