Embodiment Construction

[0905] 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.

[0906] As used herein and in the claims, the phrase "peripheral wall" as applied to the annulus refers to a surface or portion of tissue of the annulus, and / or a portion of tissue adjacent the annulus.

[0907] 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. The curved base w...

Abstract

An implant and system for reshaping an annulus includes an elongate template having one or more anchors that are directly coupled to the body of the implant or may be indirectly coupled by separate anchor array supports. When implanted, template shortening and / or reshaping the peripheral length of the annulus may improve mating of native leaflets and / or eliminate or reduce regurgitation of the valve. The template may have one or more skirts to enhance or replace defective native leaflet function. In another example, a template may be coupled to chordae tendineae attached to a ventricular wall to improve cardiac hemodynamic function. The template may be configured to prevent displacement of the anchor.
