ABSTRACT:
A bileaflet heart valve prosthesis includes an orifice body or housing defining an orifice or opening for the passage of blood therethrough. First and second leaflets or occluders are disposed in the orifice and pivotally attached to the orifice body. The first and second occluders pivot about axes between an open position and a closed position, and the axes are non-parallel. The orifice is substantially open when the first and second occluders are in their open positions and substantially closed when the occluders are in their closed position. The bileaflet heart valve may be either a central opening valve, or a side opening valve.
