ABSTRACT:
A perfusion system for off-pump coronary artery bypass is provided in order to make the off-pump coronary artery bypass easier and safer and to restrict the amount of bleeding to a degree for not affecting operations by occluding the vessel in concurrency with the perfusion, including a blood removal portion, a pump, and a perfusion portion for returning blood pumped out by the pump in the form of an injection of the blood in pulses in response to a diastolic phase of the heart.
