Abstract

A resilient self molding annuloplasty ring which may be enlarged prior to implantation to facilitate implantation within a dilated or otherwise incompetent valve annulus having sufficient contractive force to render a valve competent. The self-molding annuloplasty ring may further comprise integral attachment devices to aid in the implantation process. The resilient self-molding annuloplasty ring may be stretched to an expanded diameter and attached to a heart valve annulus, then permitted to contract to reduce the diameter of the annulus. The ring may be positioned on an insertion device that maintains the ring in its expanded diameter while attaching to the annulus.

RELATED APPLICATIONS

[0001] The present application is a continuation of Ser. No. 10 / 777,343, filed Feb. 12, 2004, entitled METHOD OF IMPLANTING A SELF-MOLDING ANNULOPLASTY RING, which is a continuation of Ser. No. 09 / 938,902, filed Aug. 24, 2001, entitled SELF-MOLDING ANNULOPLASTY RING, now U.S. Pat. No. 6,726,716, which applications are expressly incorporated herein by reference.BACKGROUND OF THE INVENTION

[0002] The human heart is hollow muscular organ having four pumping chambers separated by four heart valves. The mitral and tricuspid valves, present at the left and right atrio-ventricular junctions, open and close in response to a pressure gradient during each cardiac cycle of relaxation and contraction to control the flow of blood to a particular region of the heart.

[0003] These valves are comprised of a dense fibrous ring known as the annulus, leaflets or cusps attached to the annulus, and a complex of chordae tendineae and papillary muscles securing the leaflets. The size ...
