The Pocket Vessel Anastomosis Trainer provides surgical learners with a platform for deliberate practice of basic cardiothoracic and vascular operative skills in a safe, repeatable environment. When not in use, this compact Trainer will fit in a lab coat pocket and can be used outside of the simulated lab environment. Replaceable graft and target vessels allow for multiple anastomoses. The clear cover can be used to create a more challenging distance or angle from the anastomosis or repair site to perfect needle and needle holder angles, as well as suture placement.
