VIOLA is designed to maintain hemostasis & facilitate the completion of multiple aortic anastomoses, without the application of an aortic clamp

Sealing Element

The adaptable sealing element conforms to the aortic wall, resulting in optimal sealing.

Punching System

With it’s Integrated, over the wire aortic punch, VIOLA is the first system to allow seal of the anastomosis site prior to punching, thereby minimizing bleeding.
