Abstract
Abstract A system for locally stabilizing an anastomotic site of a vessel of a beating heart during a surgical procedure is disclosed. The system includes bonding a pad to the myocardium and attaching a control arm to the pad, all by use of a bioabsorbable adhesive. The control arm is grasped and manipulated by a retractor thereby stabilizing the anastomotic area during the surgical procedure. The pad is optional and can be ommitted in one embodiment where the control arm has feet that are directly bonded to tissue. The pad may also have barbs or can include suction cups. The pad can include a helix-shaped fastener or a mechanical fastener that can be easily linked or hooked to a surgical instrument for manipulation.
