Abstract

A medical apparatus and method for remodeling a mitral valve annulus adjacent to the coronary sinus includes an elongate body having a proximal end and a distal end. The elongate body is movable from a first, flexible configuration for transluminal delivery to at least a portion of the coronary sinus to a second configuration for remodeling the mitral valve annulus.

Claims

1. A system for remodeling a mitral valve annulus, comprising:

a delivery catheter;

an implant, detachably carried by the delivery catheter, the implant reversibly movable between a first, flexible configuration for delivery to a site adjacent the annulus of the mitral valve and a second, rigid configuration for remodeling the mitral valve annulus; and

a control on the catheter for reversibly transforming the implant between the first flexible configuration and the second remodeling configuration.

2. A system as in claim 1, wherein the implant comprises an arc when in the remodeling configuration.

3. A system as in claim 2, wherein a best fit constant radius curve corresponding to the arc has a radius within the range of from about 10 mm to about 20 mm.

4. A system as in claim 2, wherein the implant comprises a compound curve when in the remodeling configuration.

5. A system as in claim 4, wherein the compound curve comprises a “

w”

configuration.

6. A system as in claim 1, further comprising a coating on the implant.

7. A system as in claim 1, further comprising an anchor for retaining the implant at a deployment site.

8. A system as in claim 7, wherein the anchor comprises a distal extension of the implant.

9. A system as in claim 7, wherein the anchor comprises a friction enhancing surface structure for engaging adjacent tissue.

10. A system as in claim 7, wherein the anchor comprises at least one barb for piercing the wall of the vessel.

11. A system as in claim 10, wherein the barb is moveable between an axial orientation and an inclined orientation.
