Devices for placement and fixation of annuloplasty belt

A suture lock for holding a tensioning suture in tension, comprising:

• a housing having first and second through holes extending between a distal surface and a proximal surface, the first and second through holes being laterally separated, the housing having a side hole through a side surface and adjacent the proximal surface, the side hole communicating with the first through hole;
• a snare within the first through hole and adapted to move longitudinally through the first through hole, the snare having an opening;
• an anchor wire passing through a proximal portion of the first through hole and through the side hole;
• wherein the suture lock has an open configuration in which the opening of the snare is at least partially out of the first through hole and the tensioning suture passes through the opening of the suture and the second through hole of the housing and can be freely translated with respect to the snare and the second through hole of the housing, and a locked configuration in which the opening of the snare is within the first through hole and the tensioning suture is held against translation by the snare in a tortuous configuration.

An integrated delivery system for an annuloplasty belt, comprising:

• a delivery sheath;
• a pusher catheter within the delivery sheath having an internal lumen;
• a suture lock connected to a distal end of the pusher catheter;
• an annuloplasty belt having a tensioning suture, the annuloplasty belt being beside the pusher catheter within the delivery sheath;
• and
• a tensioning device for applying tension to the tensioning suture within lumen of the pusher catheter and proximal of the suture lock,
• wherein a first end of the tensioning suture is fixed to a portion of the suture lock, a middle portion of the tensioning suture passes through the suture lock and a second end of the tensioning suture is connected to the tensioning device.
