Abstract:
1. A method for the percutaneous treatment of mitral valve regurgitation by reshaping a mitral valve annulus through an arterial access site in a patient comprising the steps of: inserting a crossing catheter and a deflecting guide catheter having a lumen therethrough ending in a distal opening into the arterial access site of the patient; advancing the crossing catheter through the aortic valve into the left ventricle; advancing the deflecting guide catheter over the crossing catheter through the aortic valve into the left ventricle; withdrawing the crossing catheter from the patient; positioning the deflectable guide catheter with the distal opening pointing towards the underside of the mitral valve annulus; introducing a plication device into the arterial access site through the lumen of the deflectable guide catheter and advancing the plication device out the distal opening of the deflectable guide catheter within the left ventricle, the plication device comprising a pair of opposing jaws operable to plicate tissue; positioning the plication device at a first position on the underside of the mitral valve at or near the annulus; plicating a first portion of tissue of the mitral valve using the plication device to create a first tissue plication; and; applying a retainer to the first tissue plication.
