1. A system, for remodeling a mitral valve annulus, comprising:
- a delivery catheter; and
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 remodeling configuration for remodeling the mitral valve annulus, the implant including a guidewire lumen adapted to slideably engage a guidewire;
wherein the implant is positionable in a coronary sinus in the first flexible configuration, such that a proximal portion of the implant is positioned in a proximal part of the coronary sinus, and a distal portion of the implant is positioned in a distal part of the coronary sinus, wherein the proximal part is closer to the ostium of the coronary sinus than is the distal part;
wherein the delivery catheter is coupled to a proximal end of the implant,the delivery catheter including a control mechanism for selectively adjusting a curvature of the implant in the second remodeling configuration; and
a forming member, coupled to the implant by attachment to a distal portion of the implant and extending longitudinally along at least a portion of the implant, the forming member being configured to remain coupled to the implant in the coronary sinus after the implant is detached from the delivery catheter;
wherein, when the implant is positioned in the coronary sinus, and the forming member is advanced distally with respect to the coronary sinus, the curvature of the implant changes, thereby altering a shape of the mitral valve annulus.

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.
