Patent ID: 8551161

Claim:
A mitral valve reshaping device for treating mitral valve regurgitation at a mitral valve annulus having an initial mitral valve annulus diameter before treatment, the reshaping device comprising: a serpentine ring having a distal end, a proximal end, and a plurality of anchoring barbs disposed on and extending from apexes at the distal end of the ring, the plurality of anchoring barbs being present only at the apexes at the distal end of the ring, the serpentine ring comprising a single annular ring having a plurality of struts joined together by apexes wherein the plurality of struts have a substantially equal length forming the serpentine ring with a single amplitude, the ring having a resting configuration with a resting configuration diameter less than the initial mitral valve annulus diameter; and the ring further having an anterior side sized and shaped for alignment and placement on an anterior side of a mitral valve, and a posterior side for alignment and placement on a posterior side of a mitral valve; wherein, in a compressed configuration, the reshaping device has the anchoring barbs aligned axially and parallel with a central longitudinal axis of the reshaping device; in the resting configuration, the reshaping device has the anchoring barbs aligned radially outward from the central longitudinal axis and has the resting configuration diameter of the ring equal to a desired diameter of the mitral valve annulus after treatment, the desired diameter being smaller than the initial mitral valve annulus diameter before treatment; and, in a deployment configuration, the reshaping device is elastically expandable from the resting configuration diameter to a deployment configuration diameter of the ring greater than or equal to the initial mitral valve annulus diameter before treatment.
