HEATING/ COOLING SYSTEM FOR INDWELLING HEAT EXCHANGE CATHETER
First Claim
Patent Images
1. A heat exchange system for a heat exchange catheter, comprising:
- a heat exchange bath configured to receive a conduit carrying working fluid to and from the catheter when the working fluid is at a temperature below normal human body temperature to cool a human patient in whom the catheter is disposed; and
a gear pump in communication with the conduit for pumping the working fluid to and from the catheter.

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 two variable speed DC compressor for removing heat from the refrigerant. A gear pump circulates the working fluid to and from the catheter and is removably engaged with a pump support platform.
