ABSTRACT:
A cardiac valve prosthesis in which the inner area of the valve ring has an internal cross section continuously decreasing in flow direction. The valve ring is shaped like a nozzle, and flow disruption occurs only at the nozzle end, allowing a concentric flow discharge. Vortex formation at the jet boundary and inside the flow is inhibited. As a result, flow resistance is reduced and blood damage is minimized. A flushing channel traverses the joint cavity in order to avoid deposits of blood particles in the valvular joint.
