Abstract
A blood conduit for a pulsatile cardiopulmonary bypass pump constructed and arranged to provide a surge chamber, a pumping chamber, and a reservoir portion. The blood conduit precludes the necessity of employing a separate reservoir in a closed cardiopulmonary bypass system so that there is a direct continuity of blood from the atrium of the patient's heart to the pulsatile pump. With a preload responsive pulsatile pump, the system can be utilized with a gravity flow oxygenator.
