  • Prosthetic heart valve with increased lumen
    Patent number: 6730122
    Abstract: A prosthetic heart valve for replacing a native heart valve is provided and includes a generally circular heart valve body having an inner wall defining a lumen configured to allow blood flow therethrough. Occluders are configured to rotate about opposed occluder ends between an open position and a closed position. The minor radius arcs cooperate with the occluders to allow the occluders to block blood flow through lumen when in a closed position yet provide an increased lumen when the occluders are in an open position.
