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.

Claims

1. A valve repair system for repairing a native valve of a patient during a non-open heart procedure, the valve repair system comprising:

a delivery device having at least one lumen;

a valve repair device configured to be delivered through the lumen of the delivery device, and configured to attach to a native valve of a patient, the valve repair device comprising;

a pair of paddles that are movable between an open position and a closed position; and

a first gripping member and a second gripping member, wherein the paddles and the gripping members are configured to attach to the native valve of the patient; and

a gripper control mechanism comprising;

a first gripper control member removably attached to the first gripping member, the first gripper control member comprising a first suture and a first wire having a first loop at a distal end of the first wire, wherein the first suture extends from the delivery device and through the first loop of the first wire and is removably attached to the first gripping member, and wherein the first loop of the first wire is configured to engage the first gripping member to move the first gripping member between one or more positions; and

a second gripper control member removably attached to the second gripping member, the second gripper control member comprising a second suture and a second wire having a second loop at a distal end of the second wire, wherein the second suture extends from the delivery device and through the second loop of the second wire and is removably attached to the second gripping member, and wherein the second loop of the second wire is configured to engage the second gripping member to move the second gripping member between one or more positions.

2. The valve repair system according to claim 1, wherein the first wire and the second wire are flexible NiTi wires.

3. The valve repair system according to claim 1, wherein the first wire and the second wire each have a diameter between about 0.15 mm and about 0.3 mm.
