Abstract
A mitral annuloplasty and left ventricle restriction device is designed to be transvenously advanced and deployed within the coronary sinus and in some embodiments other coronary veins The device places tension on adjacent structures, reducing the diameter and/or limiting expansion of the mitral annulus and/or limiting diastolic expansion of the left ventricle. These effects may be beneficial for patients with dilated cardiomyopathy.

7. A method of providing a therapeutic compressive force against a tissue structure which is adjacent to a vessel wall, comprising the steps of positioning a device in the vessel;
- rotating at least a part of a forming element within the device to cause the device to exert a force against the wall of the vessel thereby exerting a force against the adjacent tissue structure; and
deploying the device within the vessel. - View Dependent Claims (8, 9, 10, 11)

12. A method of performing annuloplasty of the mitral valve comprising positioning a prosthesis in the coronary sinus;
- rotating a first portion of the device with respect to a second portion of the device to cause the device to bend into an arcuate configuration to provide a compressive force on the mitral valve annulus; and
securing the device in the arcuate configuration within the coronary sinus. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
