摘要： Embodiments of the invention provide a medical implant, and method for deploying the same, configured for placement in a body lumen such as a coronary sinus, as may be desired to treat a regurgitant mitral valve. The implant includes a proximal anchor, a distal anchor, and an elongate bridge extending between the proximal and distal anchors. The anchors are configured to be delivered to a desired deployment site within the body lumen in a collapsed or contracted condition and then expanded to engage the walls of the body lumen. The bridge is preferably a shape-changing member configured to contract after delivery into the coronary sinus for applying a compressive force to the annulus of the mitral valve. The proximal and distal anchoring mechanisms preferably overlap the proximal and distal end portions of the bridge, thereby providing the implant with a longer bridge having greater contraction.
