Abstract
Disclosed is an implantable mitral valve having an adjustable support. The support comprises a plurality of pairs of adjacent struts joined at apexes and a plurality of anchors for tissue engagement. The implant is adjustable to a first, reduced diameter for transluminal navigation and delivery to the left atrium of a heart. The implant may then expand to a second, enlarged diameter for the step of embedding the anchors into tissue surrounding and/or including the mitral valve. The implant may then be adjusted to a third, intermediate diameter, pulling the tissue radially inwardly, thereby reducing the native mitral valve annulus and supporting the prosthetic mitral valve.
