Abstract
A system for implanting a repair device onto a native valve of a natural heart to repairing the native valve of a patient during a non-open-heart procedure. The system includes a paddle and a gripping member. The paddle is movable between an open position and a closed position. The gripping member has a weakened portion and a barbed portion. The barbed portion is configured to secure the gripping member to valve tissue of the native valve of the patient. A gripper control mechanism is configured to move the gripping member between an open position and a closed position. The gripper control mechanism comprises a suture removably attached to the gripping member at a first connection point and a pushing member configured to engage the gripping member at a second connection point. The weakened portion is between the first and second connection points. The pushing member is configured to push on the gripping member and the suture is configured to pull on the gripping member to flex the weakened portion and pivot the barbed portion.
