ABSTRACT:
A heart valve prosthesis having an annular valve body, a pair of leaflet occluders mounted therein for pivoting and translational movement between closed and open positions. The leaflet occluders have mating diametrical edges and arcuate edges which engage the valve body when the leaflets are closed. Generally part conical mounting ears extend outwardly from the leaflet edge, adjacent the diametrical edge thereof. The ears are received in crescent-shaped recesses formed in the annular body. The recesses have opposed upstream and downstream surfaces for guiding the mounting ears during opening and closing of the leaflet.
