Beschreibung
Zusammenfassung:	A bi-leaflet heart valve having an improved hinge arrangement that allows the valve to respond quickly to flow reversals and minimizes fluttering of the leaflets in the open position. A pair of leaflets are slidably and pivotally mounted in a heart valve body for movement between closed and open positions. Notches in the leaflets matingly engage complementary surfaces on pivot projections extending inward from the valve body sidewall. Downstream stops interengage with complementary surfaces on the leaflets to cushion the final opening movement and reduce wear in critical locations to improve operating characteristics.
