Abstract
An improved artificial mechanical heart valve prosthesis having an improved leaflet hinge mechanism which improves washing of the hinge recess, reduces leaflet closing impact force and decreases noise and wear. A generally annular valve body having an annular interior surface extending between an inflow rim and an outflow rim thereof defines an annular orifice therethrough. A pair of leaflets are supported on said annular valve body for alternately blocking blood flow in an inflow direction when seated against the annular interior side wall in a closed position and then allowing the flow of blood through said annular orifice in a predetermined blood outflow direction when rotated into an open position.
