Annuloplasty procedures, related devices and methods

A deployable lock comprising:

• a lock body, the lock body defining a proximal opening and a pair of distal openings, wherein the proximal opening is in fluid communication with the pair of distal openings;
• a wedge, the wedge having a proximal end configured to extend outwardly from the proximal opening of the lock body, and a distal end disposed within the lock body, the wedge being configured to wedge against the lock body when the lock body and wedge are pressed together, wherein the wedge includes a re-fastenable fastener attached to and extending proximally from the wedge, wherein the re-fastenable fastener is configured to be disengaged from and re-fastened to a delivery tool to permit retrieval of the deployable lock after the deployable lock is fully released from the delivery tool;
• a pair of distally extending sleeves, each sleeve in the pair of distally extending sleeves having a proximal end coupled to a respective opening of the pair of distal openings, wherein the pair of distally extending sleeves diverge in direction from one another after extending away from the lock body;
• and
• a further sleeve that can be selectively attached to and detached from a distal end of at least one of said distally extending sleeves.
