Research Abstract

At first we developed the stent-graft within the aortic valve which could be fixed through the apex of left ventricle noninvasively, and established the suture method of the artificial graft to the descending aorta using automatic anastomosis device. We inspected the robot assisted anastomosis of the stent-graft to artificial graft. And then, we performed animal experiments using an aortic stenosis model of pigs. Namely we performed robot assisted apico-aortic bypass using the maneuver as mentioned above and evaluated suture sites and hemodynamics of pigs. Although we don't perform this method under completely endoscopic fashion and the subsequent process, we think that the fixed result which goes to the goal was obtained in the establishment of the robot assisted apico-aortic bypass using automatic anastomosis device on the beating heart.
