Abstract
A method and device for intentionally inducing whole-body hyperthermia or hypothermia in a patient for medical treatment while protecting the central nervous system from damage includes a tub for immersing the patient's body in a solution with a temperature greater than or less than normal body temperature to thereby increase or decrease the patient's body temperature. The patient's cerebral spinal fluid is circulated and maintained at temperatures less drastically altered from normal temperatures by a pump and a heater and cooler connected to the patient's spine through catheters. The patient's central nervous system blood is separated from the rest of the circulatory system and circulated and maintained at temperatures less drastically altered from normal temperatures by pumps and a heater and cooler. The remaining blood in the patient's body is circulated and temperature controlled through pumps and a heater and cooler.
