Abstract
In Off-pump CABG, internal thoracic artery is becoming main bypass graft. In most facilities, we need to clamp and hold the graft for anastomosis. However, graft can be damaged by clamping or holding. Therefore, gentle graft handling is very important. We introduced the new graft holder for sequential anastomosis. Gentle Balloon Stopper® (GBS) is compact and has easy handling. We have not experienced any traumatic graft injury. GBS is safe and useful for sequential anastomosis in OPCAB.
