Since its first implementation, minimally invasive cardiac surgery has become more and more popular among surgeons. By avoiding a complete opening of the sternum, this surgery is traditionally associated with a faster recovery, less surgical pain and less postoperative bleeding and transfusions. With its growing popularity, the need for specifically designed surgical instrumentation is evident. Since 2008, the detachable-branch Glauber clamp (Cardiovision-Trytech, Tokyo, Japan) has been used to facilitate aortic cross-clamp during minimally invasive cardiac surgery, to optimize the intraoperative visualization field without the need for adjunctive incisions of the thorax. It has been specifically developed for limited single-access minimally invasive valve surgery. The clamp is introduced through the main access incision (mini-sternotomy or mini thoracotomy) by means of a specifically designed delivery system, which is subsequently removed, leaving inside the thorax only the detachable closed branches on the aorta. Since its first implementation, the clamp has been used in numerous patients at several cardiac surgery centers worldwide. Over the years, attempts have been made to improve its ergonomics and enhance its performance. The G2 detachable-branch Glauber clamp (USB Medical, Hatboro, PA, USA) occupies a smaller space inside the thorax, has a simplified gripping mechanism and comes with detachable arms that enhance versatility with up to 10 possible clamp configurations. This article describes the characteristics of detachable-branch aortic clamps and compares them to other aortic cross-clamps that are currently available for minimally invasive cardiac surgery.
