Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
126 words
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; wherein the deforming matter comprises at least one balloon; wherein a needle is used to puncture the coronary sinus proximate the mitral valve posterior leaflet and insert the at least one balloon into the selected one of the mitral annulus and the tissue adjacent thereto; and wherein the at least one balloon is elongated and is inflated by the needle as the needle is withdrawn.
Claim 2
Independent Claim
126 words
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; wherein the deforming matter comprises at least one balloon; wherein a needle is used to puncture the coronary sinus proximate the mitral valve posterior leaflet and insert the at least one balloon into the selected one of the mitral annulus and the tissue adjacent thereto; and wherein the at least one balloon is elongated and is inflated by the needle as the needle is withdrawn.
Claim 3
Independent Claim
155 words
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; wherein the deforming matter comprises at least one balloon; wherein a needle is used to puncture the coronary sinus proximate lie mitral valve posterior leaflet and insert the at least one balloon into the selected one of the mitral annulus and the tissue adjacent thereto; wherein the at least one balloon is elongated and is inflated by the needle as the needle is withdrawn; and wherein the at least one balloon is inflated to a volume and stiffness to effect a desired conformational change to the mitral valve annulus and thereby the posterior leaflet.
Claim 4
Independent Claim
155 words
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; wherein the deforming matter comprises at least one balloon; wherein a needle is used to puncture the coronary sinus proximate lie mitral valve posterior leaflet and insert the at least one balloon into the selected one of the mitral annulus and the tissue adjacent thereto; wherein the at least one balloon is elongated and is inflated by the needle as the needle is withdrawn; and wherein the at least one balloon is inflated to a volume and stiffness to effect a desired conformational change to the mitral valve annulus and thereby the posterior leaflet.
