    摘要： A patient control system uses a patient-implanted catheter in thermal communication with a fluid bath via a circulating fluid circuit. A controller automatically controls the temperature of the fluid bath as required for selectively cooling or heating the patient in accordance with patient temperature measurements. The controller thermally decouples the catheter and patient from the fluid bath during changes in fluid bath temperatures in order to overcome the effects of system thermal mass.

    摘要： A catheter is adapted to exchange heat with a body fluid, such as blood, flowing in a body conduit, such as a blood vessel. The catheter includes a shaft with a heat exchange region disposed at its distal end. This region may include at least one balloon which is adapted to receive a remotely cooled heat exchange fluid preferably flowing in a direction counter to that of the body fluid. Embodiments including multiple balloons enhance the surface area of contact, and the mixing of both the heat exchange and the body fluid. The catheter can be positioned to produce hypothermia in a selective area of the body without cooling the entire body system. It is of particular advantage in brain surgeries where stroke, trauma or cryogenic tumors can best be addressed under hypothermic conditions. Heat pipe technology can be used to form a heat pipe heat exchange catheter. The heat pipe heat exchange catheter includes metallic bellows which allow for flexibility. The temperature control source can be portable to enable the heat pipe heat exchange catheter to be used in the ambulatory environment.

    摘要： A system for exchanging heat with the body of a patient for cooling or warming the patient provides for automatic temperature control in accordance with the monitored temperature of the patient. The system comprises a temperature control module and temperature probes for making body core temperature measurements. The body core temperature measurements are used to control the temperature of fluid circulating within the fluid circuit.
