Patent ID: 7507252

Claim:
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.
