Patent ID: 7988726

Claim:
A medical apparatus, for remodeling a mitral valve annulus of a patient adjacent to a coronary sinus, comprising: an elongate body sized and configured to be implanted, along a delivery device, at least partially within the coronary sinus of the patient; a forming element that changes the elongate body between a first shape and a second shape such that, when implanted in the coronary sinus and in the second shape, the elongate body has a best fit curve of constant radius within a range of from about 1.0 cm to about 2.0 cm and is sized and shaped to change a shape of the mitral valve annulus by exerting a force against a wall of the coronary sinus sufficient to influence the size of the mitral valve annulus; and a cardiac pacing electrode, carried by the elongate body, the electrode being configured to remain with the elongate body after the forming element changes the elongate body to the second shape and after the delivery device is entirely removed from the patient.
