Abstract
A heart valve prosthesis includes an annular body that has a fluid passageway and at least one rigid leaflet that is pivotally mounted in the passageway of the body. The leaflet is movable between a closed position wherein the fluid passageway is substantially closed and an open position wherein the fluid passageway is not substantially closed. The heart valve prosthesis has a biasing mechanism that is connected to the body and leaflet and is configured to exert a force on the leaflet to move the leaflet to the closed position before a second fluid pressure exerted on an outflow surface of the leaflet exceeds a first fluid pressure exerted on an inflow surface of the leaflet.
