Medical kit for constricting tissue or a bodily orifice, for example, a mitral valve

Abstract

A device, kit and method may include or employ an implantable device (e.g., annuloplasty implant) and a plurality of tissue anchors. The implantable device is positionable in a cavity of a bodily organ (e.g., a heart) and operable to constrict a bodily orifice (e.g., a mitral valve). Each of the tissue anchors may be guided into precise position by an intravascularly or percutaneously techniques. Constriction of the orifice may be accomplished via a variety of structures, for example an articulated annuloplasty ring, the ring attached to the tissue anchors. The annuloplasty ring may be delivered in an unanchored, generally elongated configuration, and implanted in an anchored generally arched, arcuate or annular configuration. Such may approximate the septal and lateral (clinically referred to as anterior and posterior) annulus of the mitral valve, to move the posterior leaflet anteriorly and the anterior leaflet posteriorly, thereby improving leaflet coaptation to reduce mitral regurgitation.
