First Claim
Patent Images
1. A method of treating a cardiac valve comprising:
- providing an intraannular band dimensioned for attachment within a mitral valve annulus, wherein the intraannular band comprises a body having a first end, a second end, and a convex shaped central portion, wherein the intraannular band does not comprise an annuloplasty ring; and
attaching the intraannular band within the mitral valve annulus such that the convex shaped central portion extends transversely across a coaptive edge formed by mitral valve leaflets, and such that the convex shaped central portion is convex in a direction of a ventricle.

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 cardiac valve 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; attaching the first anchoring portion to a first portion of tissue proximate the mitral annulus; and attaching the second anchoring portion to a second portion of tissue proximate the mitral annulus such that the intraannular band extends transversely across a coaptive edge formed by the closure of mitral valve leaflets during systole, and such that the convex shaped central portion is convex in a direction of the left ventricle, 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 a cardiac valve comprising:
-
providing an intraannular band dimensioned for attachment within an intraannular plane of a heart valve annulus, wherein the intraannular band comprises a body having a first end, a second end, and a convex shaped central portion; and attaching the intraannular band within the intraannular plane of the heart valve 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, and such that the convex shaped central portion is convex in a direction of an outflow side of the intraannular plane to support the two or three valve leaflets. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
