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.

Claims14

Dependent claims

A method of modifying a heart valve of a patient, comprising:

advancing an access catheter through the patient's vasculature into the heart from a vascular access point remote from the heart, the access catheter having a central lumen and a distal end;
extending a delivery catheter through the central lumen of the access catheter through the distal end of the access catheter, the delivery catheter comprising an actuatable grasping element and a lumen extending through the actuatable grasping element;
deploying a structure from the delivery catheter through the lumen extending through the actuatable grasping element into a gutter on the ventricular side of the annulus of the heart valve, the structure adapted to modify the annulus so as to reduce regurgitation in the heart valve;
holding leaflets of the heart valve together using the actuatable grasping element of the delivery catheter so as to reduce regurgitation in the heart valve during the deployment of the structure from the delivery catheter;
and
withdrawing the actuatable grasping element of the delivery catheter after the structure is deployed in the gutter of the ventricular side of the annulus of the heart valve, such that the structure remains deployed in the gutter of the annulus once the actuatable grasping element is withdrawn.
