First Claim
1. A valve repair device for repairing a native valve of a patient, the valve repair device comprising:
- a base assembly comprising a plurality of pivoting links and a shaft, wherein the pivoting links are moved by the shaft;
a pair of paddles attached to the base assembly, wherein the movement of the pivoting links moves the paddles between an open position and a closed position;
a pair of gripping members attached to the base assembly, wherein the paddles and the gripping members are configured to attach to valve leaflets of the patient;
at least one spacer element that surrounds the shaft and is disposed between the pair of gripping members;
wherein the spacer element is made from at least one material selected from the group of materials consisting of braided mesh, fabric, biocompatible material, foam, and pericardial tissue;
wherein the spacer element fills a space between the gripping members when the paddles are in the closed position.

Abstract
A system for implanting a repair device onto a native valve of a natural heart to repair the native valve of a patient during a non-open-heart procedure. The system includes a base assembly having a plurality of pivoting links, a pair of paddles attached to the base assembly, a pair of gripping members attached to the base assembly, and at least one coaptation or spacer element disposed between the pair of gripping members. Movement of the pivoting links of the base assembly causes the paddles to move between an open position and a closed position. The paddles and the gripping members are configured to attach to valve leaflets of the patient. The coaptation or spacer element is configured to fill at least a portion of a gap between the valve leaflets of the patient.
