Claim Text:
1. A system for managing the temperature of a person using an intravascular heat exchanger inserted into the lumen of a body vessel of a patient, comprising: a refrigeration circuit comprising a compressor for pumping and compressing a first heat exchange fluid through the refrigeration circuit, a condenser, an expansion valve, and a first side of a first heat exchanger; a secondary fluid circuit comprising a pump for pumping a second heat exchange fluid through the secondary fluid circuit, a second side of the first heat exchanger, a first side of a second heat exchanger, and a heat exchange block; a reversible heater/cooler in thermal communication with the heat exchange block such that the reversible heater/cooler may modulate the temperature of the heat exchange fluid in the secondary fluid circuit by adding heat to or removing heat from the heat exchange block; an intravascular fluid circuit comprising an intravascular heat exchanger having a fluid input port and a fluid output port, a pump for pumping a third heat exchange fluid through the intravascular fluid circuit, and a second side of the second heat exchanger; and a controller having a processor configured by software commands to receive temperature indications related to the temperature of a patient from a sensor and to control operation of the heater/cooler in accordance with a target temperature.
