Abstract
One aspect of the invention is a method of treating mitral valve regurgitation in a patient. The method includes the steps of delivering a tissue shaping device to the patient'"'"'s coronary sinus in an unexpanded configuration within a catheter having an outer diameter no more than nine or ten french, with the tissue shaping device including a connector disposed between a distal expandable anchor comprising flexible wire and a proximal expandable anchor comprising flexible wire, the device having a length of 60 mm or less; and deploying the device to reduce mitral valve regurgitation, such as by anchoring the distal expandable anchor by placing the distal expandable anchor flexible wire in contact with a wall of the coronary sinus, e.g., by permitting the distal expandable anchor to self-expand or by applying an actuating force to the distal expandable anchor and possibly locking the distal expandable anchor after performing the applying step. The invention also includes a device for performing the method.
