Abstract: A system for controlling patient temperature uses a central venous line catheter having axially spaced distal and proximal heat exchange balloons. The central venous line catheter is provided with one or more lumens for providing access to the central blood supply of the patient, and with additional lumens for communicating heat exchange fluid to the balloons. Heat exchange fluid temperature is controlled through a feed back loop in which patient temperature is sensed and used to control a temperature control unit comprising a heating device and/or a cooling device in heat exchange relationship with the heat exchange fluid. A tubing set transports the heat exchange fluid between the central venous line and the temperature control unit, with a pump serving to circulate the fluid in a closed fluid circuit in the system.

Abstract: A heat exchange catheter has a catheter body with an inflow lumen, an outflow lumen, and an infusion lumen. A first heat exchange balloon helically wraps around at least a portion of the catheter body in fluid communication with the inflow lumen. A second heat exchange balloon helically wraps around at least a portion of the catheter body in fluid communication with the outflow lumen. The first and second balloons form a gap there between to facilitate infusion of fluid into the blood stream of the patient via an infusion port formed within the gap.
