Systems and methods for preserving a human organ for transplantation

An organ preservation system comprising:

• a pump coupled to an actuator configured to provide a force to said pump;
• a cassette configured to hold an organ, said cassette coupled to said pump;
• said pump comprising an outlet for providing a perfusate to the organ when the organ is received in said cassette and coupled to said pump and an inlet for receiving the perfusate returning from the cassette;
• said pump configured to provide a pulsatile pumping force to the perfusate via a pumping stroke followed by a return stroke;
• said pumping stroke causing said pump to collapse to force a flow of the perfusate through said outlet to the organ, said pump collapsing in a direction of the flow of the perfusate;
• and
• said return stroke allowing the perfusate to enter said pump through said inlet and said return stroke avoiding providing the perfusate through said outlet.

A method for preserving an organ, the method comprising:

• an actuator providing an actuating force to a pump to cause a pumping stroke to cause a collapse of the pump to send a flow of a perfusate from the pump through an outlet of the pump to an organ received in a cassette, the pump collapsing in a direction of the flow of the perfusate;
• the actuator retreating away from the pump to remove the actuating force from the pump;
• and
• the pump returning toward a starting position of the pump and receiving perfusate through an inlet of the pump while avoiding sending fluid through the outlet.
