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 surgical delivery instrument, a valve repair device, and a gripper control mechanism. The surgical delivery instrument has at least one lumen. The valve repair device is configured to be delivered through the lumen of the surgical delivery instrument and to be attached to a native valve of a patient. The valve repair device has a pair of paddles, and first and second gripping members. The paddles are movable between an open position and a closed position. The paddles and the first and second gripping members are configured to attach to the native valve of the patient. The gripper control mechanisms each include a suture and a wire having a loop at a distal end. The suture extends from the surgical delivery instrument and through the loop of the wire. The suture is removably attached to the gripping member. The loop of the wire is configured to engage the gripping member to move the gripping member between one or more positions.
