Abstract
A system for extracorporeal perfusion of human organs wherein a pulsatile flow of cold perfusate is circulated through an organ intended for transplantation. The system includes a perfusion chamber, a heat exchanger comprising an ice water bath containing a coil of tubing through which perfusate is circulated, and a pulsatile pump interposed in the line between the heat exchanger and the perfusion chamber, downstream of that exchanger, for drawing cold perfusate through the exchanger and directing it in a series of regular pulses to the organ. The system is particularly adapted for use in a compact portable perfusion unit.
