Abstract
Abstract The invention provides a sewing cuff assembly (32) for mounting to the body (22) of a heart valve prosthesis (20). The sewing cuff assembly comprises a resiliently deformed spring (42) for exerting a force directed toward the orifice structure. When a torque is applied to the valve (20), the force results in a rotation-resisting torque sufficient to resist rotation during normal operation of the valve (20) after implantation but low enough to permit assisted rotation, as during surgery.
