Abstract

See full text

A polyurethane heart valve has a semirigid frame composed of a base ring and three struts, and an elastomeric membrane integral and unitary with the frame, the contours of which make up three leaflets of the valve. The leading edges of the leaflets which form the commissure line are reinforced with a narrow elastomer band. The leaflets are further reinforced by radiating lines projected from the frame into the leaflet and which simulate collagen formation in natural leaflets. In addition, the transition between the frame and the leaflets is tapered.
