1. A method of treating aortic regurgitation, the method comprising:
- implanting in the aortic annulus a transvalvular band comprising an elongate and arcuate body having a first end, a first anchoring portion located proximate the first end, a second end, and a central portion, the central portion displaced out of the plane containing the first end and the second end, wherein the central portion comprises a convex arcuate shape and extends transversely across a coaptive edge formed by the closure of the aortic valve leaflets; and
attaching the first anchoring portion to one portion of the aortic annulus, wherein attaching the anchoring portion does not affect the size and shape of the aortic annulus.

Abstract
Aortic regurgitation can be treating by implanting in the aortic annulus a transvalvular intraannular band. The band 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 positioned so that it extends transversely across a coaptive edge formed by the closure of the aortic valve leaflets. The band may be implanted via translumenal access or via thoracotomy.

9. A method of treating an aortic valve, comprising the steps of:
-
providing a transvalvular band having a convex side, a central portion having a convex arcuate shape, and a projection extending from the convex side; and securing the band to a valve annulus such that the convex side extends across the plane of the annulus in the direction of the aorta and transversely across a coaptive edge formed by the closure of the aortic valve leaflets, 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, wherein securing the band to the valve annulus does not substantially affect the size and shape of the aortic annulus. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of moving aortic 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 aortic valve annulus, the band comprising a central portion having a convex arcuate shape; and attaching the band within the plane of the annulus such that a portion of the band extends into the aortic side of the plane to support the leaflets and elevate the position of the coaptive edges in the direction of the aorta during valve closure, wherein the band extends transversely across a coaptive edge formed by closure of the aortic valve leaflets. - View Dependent Claims (16, 17, 18, 19, 20)
