Patent ID: 7192443

Claim:
A medical device for reshaping a mitral valve annulus in a body, comprising: a shape-changing member having proximal and distal ends and biased to move from a first stretched configuration to a second configuration that is bent and shortened; a proximal self-expandable stent attached to the proximal end of the shape-changing member along a circumferential portion of the proximal stent and a distal self-expandable stent attached to the distal end of the shape-changing member along a circumferential portion of the distal stent, the proximal and distal self-expandable stents configured for anchoring the proximal and distal ends of the shape-changing member within a coronary sinus; and a resorbable material disposed along the shape-changing member, the resorbable material configured to maintain the shape-changing member in the first stretched configuration; wherein, in the second configuration, the shape-changing member is configured to apply sufficient force to the coronary sinus to reshape the mitral valve annulus; wherein the resorbable material has a design parameter to delay the bending and shortening to the second configuration until after expanded portions of the proximal and distal stents have sufficiently grown into an inner wall of the coronary sinus to support the bending and shortening to the second configuration.
