Abstract
Devices and methods for treating mitral regurgitation by reshaping the mitral annulus in a heart. One preferred device for reshaping the mitral annulus is provided as an elongate body having dimensions as to be insertable into a coronary sinus. The elongate body includes a proximal frame having a proximal anchor and a distal frame having a distal anchor. A ratcheting strip is attached to the distal frame and an accepting member is attached to the proximal frame, wherein the accepting member is adapted for engagement with the ratcheting strip. An actuating member is provided for pulling the ratcheting strip relative to the proximal anchor after deployment in the coronary sinus. In one preferred embodiment, the ratcheting strip is pulled through the proximal anchor for pulling the proximal and distal anchors together, thereby reshaping the mitral annulus.
