ABSTRACT:
An organ preservation apparatus including an organ-receiving chamber, a pulsatile pump in continuous uninterrupted liquid communication with the organ-receiving chamber, and a fluid delivery tube interconnected between the organ-receiving chamber and the pulsatile pump for passing the organ preservation fluid from the organ-receiving chamber to the pulsatile pump. The pulsatile pump is configured to pass an organ preservation fluid to the organ-receiving chamber in a dichrotic pulse pattern. The organ-receiving chamber has an outer box with an insulated interior area, an organ-receiving cassette removably contained within the insulated interior area, and a lid detachably fastened to the outer box. The pulsatile pump includes a bladder pump, a motor, and a cam connected to the motor. The cam is connected to an actuator so as to compress the bladder pump is a dichrotic pulse pattern. A pressure transducer is connected to the fluid passageway between the pulsatile pump and the organ-receiving chamber so as to measure diastolic and systolic fluid pressure.
