Figure 1 Illustration of the annuloplasty device. The distal and proximal anchors are collapsed before insertion and the device is delivered to the coronary sinus (CS) via a guide catheter. The distal anchor is deployed in the distal coronary sinus and locked. Tension is then applied via the delivery system until satisfactory acute efficacy with stable coronary perfusion is documented. The proximal anchor is then deployed and locked in the proximal CS. The delivery system is then uncoupled and removed.
