Abstract
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.
