Method and apparatus for reducing mitral regurgitation
First Claim
1. A method for reducing mitral regurgitation, the method comprising deploying deforming matter into a selected one of (i) a mitral valve annulus adjacent a posterior leaflet and (ii) tissue adjacent the mitral valve annulus proximate the posterior leaflet, to cause a conformational change in the annulus, and thereby a conformational change in the posterior leaflet, to increase mitral valve leaflet coaptation.

Abstract
A method for reducing mitral regurgitation includes deploying deforming matter into a selected one of (i) a mitral valve annulus adjacent a posterior leaflet, and (ii) tissue adjacent the mitral valve annulus and proximate the posterior leaflet, to cause conformational change in the mitral valve annulus to increase mitral valve leaflet coaptation.

17. An assembly for reducing mitral regurgitation, the assembly comprising:
-
a delivery catheter adapted for insertion into a coronary sinus;
a needle for movement through said delivery catheter and adapted to penetrate the coronary sinus and enter tissue between the coronary sinus and a mitral valve annulus adjacent a posterior leaflet, and adapted to enter the mitral valve annulus, and deforming matter adapted to be carried by the needle and deployed in at least one of the tissue and the mitral valve annulus. - View Dependent Claims (18)
