Abstract
A portable perfusion system for organ preservation comprising a cart on which a refrigeration unit, a pump unit and a cassette are mounted with the pump and cassette being removable for separate transport. The cassette includes an organ receptacle, a heat exchanger, a membrane oxygenator, a bubble trap and an ice deposit area. The heat exchanger is connected to the refrigeration unit and the perfusate is pumped by a non-pulsatile pump through the heat exchanger to the bubble trap and, in turn, to the organ. An oxygen supply on the cart supplies oxygen to the membrane oxygenator which functions to oxygenate the perfusate.
