Abstract
A device, kit and method may employ an implantable device (e.g., annuloplasty implant) and a tool to implant such. 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). Tissue anchors are guided into precise position by an intravascularly deployed anchor guide frame and embedded in an annulus. Constriction of the orifice may be accomplished via a variety of structures, for example by cinching a flexible cable or anchored annuloplasty ring, the cable or ring attached to the tissue anchors. The annuloplasty ring may be delivered in a generally elongated configuration, and implanted in an anchored generally arch, arcuate or annular configuration. Such may move a posterior leaflet anteriorly and an anterior leaflet posteriorly, improving leaflet coaptation to eliminate mitral regurgitation.
