PROSTHETIC HEART VALVE WITH INCREASED LUMEN

摘要

A prosthetic heart valve (10) for replacing a native heart valve is provided and includes a generally circular heart valve body (12) having an inner wall (14) defining a lumen (16) configured to allow blood flow therethrough. Occluders (40, 42) are configured to rotate about opposed occluder ends between an open position and a closed position. Minor radius arcs (24) in the body (12) cooperate with the occluders (40, 42) to allow the occluders (40, 42) to block blood flow through lumen when in a closed position yet provide an increased lumen (16) when the occluders (40, 42) are in an open position.
