Device and methods for endoscopic annuloplasty
First Claim
1. A method of modifying a heart valve of a patient, comprising:
- advancing a catheter through the patient'"'"'s vasculature into the heart from a vascular access point remote from the heart, the catheter having at least one structure releasably coupled thereto;
deploying the structure from the catheter into a gutter on a ventricular side of annulus of the heart valve, the structure adapted to modify the annulus so as to reduce regurgitation in the heart valve; and
in combination with deploying the structure, holding leaflets of the heart valve together so as to reduce regurgitation in 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. The tissue structures can be temporarily modified prior to permanent modification. For example, opposed valve leaflets may be temporarily grasped and held into position prior to permanent attachment. In one aspect, a structure is deployed in a gutter region of the valve annulus to modify the shape of the valve.

15. A method of modifying a heart valve of a patient, comprising:
-
advancing a catheter through the patient'"'"'s vasculature into the heart from a vascular access point remote from the heart, the catheter having an annuloplasty device releasably coupled thereto;
performing an intervention on a gutter on a ventricular side of the heart valve to modify an annulus of the heart valve and reduce regurgitation in the heart valve;
in combination with performing an intervention, modifying a spatial relationship between a first valve leaflet and a second valve leaflet of the heart valve so as to reduce regurgitation in the heart valve. - View Dependent Claims (16, 17, 18, 19)
