TRANSVALVULAR INTRAANNULAR BAND FOR VALVE REPAIR
First Claim
1. A transvalvular intraannular band, the transvalvular band comprising:
- an elongate and arcuate 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 central portion, the central portion displaced transversely from a plane which includes the first end and the second end;
wherein the first end and the second end are configured to be attached to the mitral valve annulus within the plane of the annulus and the central portion is configured to support the mitral valve leaflets at a point displaced toward the ventricle from the plane.

Abstract
Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band having an elongate and arcuate body. The elongate and arcuate body has 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 central portion. The central portion is displaced from the plane containing the first end and the second end. The transvalvular band is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets and the central portion is displaced towards the left ventricle relative to the first anchoring portion and the second anchoring portion. The ventricular direction displacement moves coaption to an earlier point in the cardiac cycle.

5. A method of treating mitral valve prolapse, the method comprising:
-
implanting in the mitral annulus an intraannular band comprising an elongate and arcuate 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 central portion, the central portion displaced out of the plane containing the first end and the second end; attaching the first anchoring portion to one portion of the mitral annulus; and attaching the second anchoring portion to another portion of the mitral annulus such that the intraannular band extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets and the central portion is displaced towards the left ventricle relative to the first anchoring portion and the second anchoring portion.

6. A method of treating a mitral valve, comprising the steps of:
-
providing a transannular band having a convex side and a projection extending from the convex side; securing the band to a valve annulus such that the convex side extends across the plane of the annulus in the direction of the ventricle, and the projection extends in a downstream blood flow direction, so that a first leaflet closes against a first side of the projection and a second leaflet closes against a second side of the projection. - View Dependent Claims (7, 8)

9. A method of moving mitral valve leaflet coaption to an earlier point in the cardiac cycle, comprising the steps of:
-
providing an intraannular, transvalvular band dimensioned for attachment within the plane of the mitral valve annulus; attaching the band within the plane of the annulus such that a portion of the band extends into the ventricular side of the plane to support the leaflets and elevate the position of the coaptive edges in the direction of the ventricle during valve closure. - View Dependent Claims (10, 11)
