Transvalvular intraanular band for ischemic and dilated cardiomyopathy
First Claim
Patent Images
1. A method of treating ischemic or dilated cardiomyopathy, comprising the steps of:
- providing an intraannular band dimensioned for attachment within an intraannular plane of a mitral valve annulus of a mitral valve, wherein the band comprises a body having a first end, a second end, and a convex shaped central portion, wherein the band does not comprise an annuloplasty ring; and
attaching the band within the intraannular plane of the annulus such that the convex shaped central portion extends transversely across a coaptive edge formed by mitral valve leaflets of the mitral valve, and such that the convex shaped central portion is convex in the direction of the ventricular side of the intraannular plane to support the leaflets and elevate the position of the coaptive edge in the direction of the ventricle during mitral valve closure.

Abstract
Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band. The band is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets, to inhibit prolapse into the left atrium. At least one marginal chordae is severed, to permit leaflet closure against the band.

9. A method of treating a mitral valve, the method comprising:
-
implanting in a mitral annulus an intraannular band comprising a body having a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a convex shaped central portion, wherein the convex shaped central portion is displaced out of a reference plane containing the first and second ends, wherein said reference plane is configured to coincide with an intraannular plane of the mitral valve when the band is implanted; attaching the first anchoring portion to a first portion of tissue proximate the mitral annulus within the intraannular plane; and attaching the second anchoring portion to a second portion of tissue proximate the mitral annulus within the intraannular plane such that the intraannular band extends transversely across a coaptive edge formed by the closure of mitral valve leaflets of the mitral valve during systole, and such that the central portion is convex in the direction of the left ventricle relative to the reference plane to elevate the position of the coaptive edge in the direction of the ventricle during valve closure, wherein attaching the first and second anchoring portions does not affect the size and shape of the mitral annulus. - View Dependent Claims (10, 11, 12)

13. A method of treating ischemic or dilated cardiomyopathy, comprising the steps of:
-
providing an intraannular band dimensioned for attachment within an intraannular plane of a heart valve annulus of a heart valve, wherein the band comprises a body having a first end, a second end, and a convex shaped central portion, wherein the band does not comprise an annuloplasty ring; and attaching the band within the intraannular plane of the annulus such that the convex shaped central portion extends out of a reference plane including a portion of the first and second ends, such that the convex shaped central portion extends transversely across a coaptive edge formed by two or three valve leaflets of the heart valve, and such that the convex shaped central portion is convex in the direction of the outflow side of the intraannular plane to support the two or three valve leaflets and elevate the position of the coaptive edge in the direction of outflow during valve closure. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
