Detachable Aortic Clamp for Minimally Invasive Cardiac Surgery

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 i
