Abstract
A cooling system for an indwelling heat exchange catheter includes a heat exchange bath that is configured to receive a conduit that carries saline to and from the catheter. A heating/cooling fluid is in the bath and exchanges heat with the saline. The heating/cooling fluid flows through a heat exchanger that includes a refrigerant and a variable speed DC compressor for removing heat from the refrigerant. A coolant pump circulates the heating/cooling fluid between the heat exchanger and the heat exchange bath.
