A simple, lightweight, inexpensive, easy-to-construct, vascular suture bow will maintain a preset, self-centering tension on the vessel wall or the vessels being anastomosed, even on a beating heart, a feat that cannot be duplicated by an assistant. Though designed for coronary artery surgery, the bow is useful for all anastomotic procedures, such as in organ transplant or peripheral arterial reconstructive surgery.
