Methods And Apparatus For Cardiac Valve Repair
First Claim
1. A method of modifying a heart valve of a patient, comprising:
- advancing a delivery catheter through the patient'"'"'s vasculature into the heart from a vascular access point remote from the heart, wherein at least one anchor is removably attached to a distal region of the catheter;
placing a plurality of the anchors about the annulus of the heart valve using the delivery catheter;
causing the anchors to modify the shape of the heart valve.

Abstract
The methods, devices, and systems are provided for performing endovascular repair of atrioventricular and other cardiac valves in the heart. Regurgitation of an atrioventricular valve, particularly a mitral valve, can be repaired by modifying a tissue structure selected from the valve leaflets, the valve annulus, the valve chordae, and the papillary muscles. These structures may be modified by suturing, stapling, snaring, or shortening, using interventional tools which are introduced to a heart chamber. Preferably, the tissue structures will be temporarily modified prior to permanent modification. For example, opposed valve leaflets may be temporarily grasped and held into position prior to permanent attachment.

8. A method of modifying a valve annulus in a heart, the method comprising:
-
providing an anchor delivery device having a plurality of anchors coupled thereto; contacting the anchor delivery device with a length of the valve annulus; delivering the plurality of coupled anchors from the anchor delivery device to secure the anchors to the annulus; and drawing the anchors together to circumferentially tighten the valve annulus. - View Dependent Claims (9, 10, 11)
