Abstract
An intravascular support device includes a support or reshaper wire, a proximal anchor and a distal anchor. The support wire engages a vessel wall to change the shape of tissue adjacent the vessel in which the intravascular support is placed. The anchors and support wire are designed such that the vessel in which the support is placed remains open and can be accessed by other devices if necessary. The device provides a minimal metal surface area to blood flowing within the vessel to limit the creation of thrombosis. The anchors can be locked in place to secure the support within the vessel.

9. A method of manipulating the mitral valve, comprising the steps of:
- providing a catheter, having a prosthesis thereon, the prosthesis having a first tissue anchor and a second tissue anchor;
inserting the catheter into the venous system;
transluminally advancing the prosthesis into the coronary sinus;
attaching the first and second tissue anchors to the wall of the coronary sinus; and
manipulating the prosthesis to exert a lateral force on the wall of the coronary sinus in between the first and second tissue anchors. - View Dependent Claims (10, 11, 12)

13. A method of performing annuloplasty of the mitral valve comprising positioning a prosthesis in a curved portion of the coronary sinus;
- engaging a proximal tissue anchor and a distal tissue anchor on the device into tissue on an inside radius of the curve;
manipulating a first portion of the device with respect to a second portion of the device to provide a compressive force on the inside radius of the curve in between the first and second anchors; and
securing the device to maintain the compressive force within the coronary sinus. - View Dependent Claims (14, 15, 16, 17, 18)
