Anastomosis Device Benefits Bypass Procedure

A new device to assist anastomosis was used recently for the first time in a beating heart coronary artery bypass procedure at the Free University Hospital in Amsterdam (The Netherlands) to create hemostasis and facilitate the proximal anastomosis of the bypass vessel to the aorta.

The new device is designed to eliminate the need for partial-occlusion clamping during both on-pump and off-pump procedures. It can provide the surgeon with a stable, bloodless field and improve hemodynamics, compared to partial occlusion clamps, says Novare Surgical Systems, Inc. (Cupertino, CA, USA), which developed the device. Partial occlusion clamps are associated with a number of postoperative complications. The Enclose Anastomotic Assist Device, as the device is called, offers the ability to access the aorta in a horizontal plane with the opposite aortic wall out of the way, making fitting and suturing easier. Novare notes that it also has the potential for less trauma to the aorta, while allowing the surgeon to create hand-sutured anastomoses.

"The device only needs a small entry in the proximal aorta, enabling you to make a safe and sound anastomosis,” said E.K. Jansen, M.D., cardiac surgeon at the Free University Hospital. "It is very easy to remove and clearly less traumatic than a side clamp.”
