Abstract
The present invention provides a device for safely and completely performing the anastomosis of the bypass graft to the coronary artery on the beating heart with good patency, which comprises: a means for rotating a heart to obtain excellent exposure of the target coronary artery to be anastomosed and absorbing the portion of the myocardium to stabilize the anastomosis area without reducing cardiac output; a means for perfusion to the distal myocardium during the anastomosis of the bypass graft to the coronary artery; and a means for compressing the coronary artery proximal and distal to the site of the anastomosis at a minimum stress to perform occlusion for obtaining bloodless operative field.
Claims8
A device for coronary artery bypass grafting on a beating heart, used for performing anastomosis of a bypass graft to a coronary artery, which device comprises:
- a means for rotating a heart for obtaining good exposure of the coronary artery and absorbing motion of the beating heart to provide motion reduction of an area of performing the anastomosis;
- a means for providing blood flow to the distal myocardium during the anastomosis of the bypass graft;
- and a means for compressing the coronary artery to perform proximal and distal occlusion of anastomosis portion, to stop blood flow through the coronary artery to provide a bloodless operative field during the anastomosis of the bypass graft.
