Patent ID: 7637945

Claim:
A system for treatment of mitral valve dilatation, comprising: an elongate body including a distal anchor configured to be positioned within and anchored to a coronary sinus of a heart adjacent to a mitral valve annulus within the heart, a proximal anchor configured to be positioned within the heart proximal to the distal anchor and adjacent to the mitral valve annulus within the heart, and an interconnecting part permanently attached to the distal and proximal anchors; a cover sheet having a distal end, a proximal end and a lumen that receives the elongate body, the cover sheet being guidable into the coronary sinus adjacent to the mitral valve annulus and being retractable for deploying the distal and proximal anchors of the device within the coronary sinus adjacent to the mitral valve annulus; and a detachable delivery instrument coupled to at least the proximal anchor of the elongate body and extending proximally though the lumen and out of the catheter proximal end, the delivery instrument being configured for positioning and releasing the elongate body in the coronary sinus; wherein the elongate body is configured to effect the shape of the mitral valve annulus after deployment in the coronary sinus.
