SYSTEM USING A HELICAL RETAINER IN THE DIRECT PLICATION ANNULOPLASTY TREATMENT OF MITRAL VALVE REGURGITATION
First Claim
1. A system for the treatment of mitral valve regurgitation through direct plication annuloplasty of a patient comprising:
- a deflecting guide catheter having an elongate body with lumen therethrough ending in a distal opening for insertion through the aortic valve into the left ventricle of the patient;
a plication device having a set of opposing jaws operable to plicate tissue in the mitral valve of the patient;
wherein the plication device comprises at least one helical retainer for retaining plications in tissue created by the opposing jaws.

Abstract
A system for using a helical retainer in the treatment of mitral valve regurgitation by reshaping the mitral valve annulus using one or more plications of annular tissue each fixed by a retaining clip is described. The system includes four devices to achieve such percutaneous direct plication annuloplasty. The first is a preferably prolapsable crossing catheter. Second, a deflecting guide catheter is used to provide a means for guiding the plication device into proper position at the subvalvular region of the mitral valve annulus. Third, the plication device is then used to make plications in at or near the subvalvular region of the mitral valve annulus. Fourth, a helical retainer clip deployed by the plication device in order to retain the plicated tissue in the plicated form. Alternatively, the fourth device is a retainer delivery catheter that enables delivery of a helical retainer over the outside of the plication device.
