A heat exchange fluid supply system for supplying a heat exchange fluid to an
intravascular
heat exchange catheter includes a disposable cassette having a bulkhead and an
external heat exchanger, and which is configured to operate in combination with
a reusable master control unit. The bulkhead includes a reservoir section and a
pump section. The reservoir section is provided with a means to monitor the amount
of heat exchange fluid that is in the system. The bulkhead provides the mechanism
for priming the system with heat exchange fluid from an external source and for
circulating fluid to the catheter in a closed circuit. The pump section is configured
to allow for pumping of heat exchange fluid at a constant pressure.
