摘要:
The invention provides a sewing cuff assembly for mounting to the body of a heart valve prosthesis. The sewing cuff assembly comprises a resiliently deformed spring for exerting a force directed toward the orifice structure. When a torque is applied to the valve, the force results in a rotation-resisting torque sufficient to resist rotation during normal operation of the valve after implantation but low enough to permit assisted rotation, as during surgery.
