Abstract
A perfusion pump system for providing perfusate to an organ of a human body includes an actuator coupled to a pump to provide an actuating force to the pump. The pump includes an outlet for providing a perfusate to an organ coupled to the pump and an inlet for receiving the perfusate. The pump is configured to provide a pulsatile pumping force to the perfusate via a pumping stroke in response to the actuating force. The pumping stroke is followed by a return stroke. The pumping stroke causes the pump to collapse to force a flow of the perfusate through the outlet to the organ. The pump collapses in the direction of the flow of the perfusate. The return stroke allows the perfusate to enter the pump through the inlet and the return stroke of ways providing the perfusate through the outlet.
