Coronary sinus approach for repair of mitral valve regurgitation

A system for treating cardiac valve regurgitation, comprising:

• a delivery catheter;
• a treatment device disposed within a lumen of the delivery catheter;
• the treatment device having a tubular member including a lumen there through and a locking mechanism disposed upon an outer surface of the tubular member, and a compression device carried on the tubular member, the compression device being transformable to a compression configuration responsive to application of an axial displacement and is locked in the compression configuration with the locking mechanism;
• a release mechanism releasably connected to the treatment device;
• the release device having a pull tube slidably disposed within the push tube and having at least one latch finger disposed at a distal end of the pull tube, and a groove at a proximal end of the tubular member for receiving the at least one latch finger, wherein the at least one latch finger is held in engagement with the groove by the push tube and is released from the groove by sliding the push tube over the pull tube to expose the at least one latch finger and
• a push tube slidably disposed within the delivery catheter for applying an axial force to the treatment device.
