Isolated extra-corporeal coronary perfusion circuit for use during off-pump coronary artery bypass grafting.

Cardiovascular surgery would not have developed into its present form without the heart-lung machine. In coronary artery bypass grafting (CABG), cardiopulmonary bypass allows accurate, all site, complete revascularization in a way convenient to the surgeon. The aim of this circuit is to find new ways to reduce invasiveness of CABG and to create new basis conditions for successful coronary bypass grafting on the beating heart.
