摘要： A heart valve prosthesis having a valve housing providing a lumen therethrough. The valve housing has a first annulus on one end and a second annulus on the other end spaced apart from the first annulus. A suture cuff is used for attaching the valve housing to heart tissue of a patient. The cuff is attached between the first annulus and the second annulus. The cuff is positioned such that prosthesis is attached in a supra-annular position relative to a tissue annulus of the heart. The design allows for an increased valve lumen.

摘要： 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.
