Embodiment Construction

[0416] As used herein and in the claims, the phrase "annulus" refers to the annular tissue structure surrounding the opening at the base of a heart valve that supports the leaflets of the valve. For example, the mitral valve, tricuspid valve, aortic valve, pulmonary valve, venous valve annulus, and other valve annuluses in the body. In the mitral valve, the annulus is usually a saddle-shaped structure that supports the leaflets of the mitral valve.

[0417] As used herein and in the claims, the phrase "peripheral wall" as applied to the valve annulus refers to a surface or portion of tissue of the valve annulus, and / or a portion of tissue adjacent the valve annulus.

[0418] A "recess" as used herein and in the claims refers to a depression or dimple formed in the surface of a template. The recesses may comprise flat areas connected at an angle, eg linear, but will more typically have a curved bottom that incorporates a pair of generally straight and / or curved walls or legs. ...

Abstract

A system for reshaping a valve annulus includes an elongate template having a length along a longitudinal axis and at least one concavity in a generally lateral direction along said length. The pre-shaped template is positioned against at least a region of an inner peripheral wall of the valve annulus, and at least one anchor on the template is advanced into a lateral wall of the valve annulus toreposition at least one segment of the region of the inner peripheral wall of the valve annulus into said concavity. In this way, a peripheral length of the valve annulus can be foreshortened and / or reshaped to improve coating of the valve leaflets and / or to eliminate or decrease regurgitation of a valve.
