SYSTEMS AND METHODS FOR PRESERVING A HUMAN ORGAN FOR TRANSPLANTATION

摘要

A perfusion pump system for providing perfusate to an organ of a human body includes an actuator (120, 320) coupled to a pump (60) to provide an actuating force to the pump (60). The pump includes an outlet (106, 306) for providing a perfusate to an organ coupled to the pump and an inlet (105, 305) for receiving the perfusate. The pump (60) 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 (60) to collapse to force a flow of the perfusate through the outlet (106, 306) to the organ. The pump (60) collapses in the direction of the flow of the perfusate. The return stroke allows the perfusate to enter the pump (60) through the inlet (105, 305) and the return stroke of ways providing the perfusate through the outlet (106, 306).
