ABSTRACT:
The invention relates generally to methods and apparatus for inducing hypothermia in an animal. Known methods for inducing hypothermia all involve cooling the outside or inside of an animal, sometimes in conjuction with drugs that disable the animal's homeostatic responses. The present invention is directed to a method and apparatus for applying heat to the hypothalamus of a warm-blooded animal in order to utilize the physiological mechanisms that regulate body temperature to effect a compensatory cooling response, thereby lowering body temperature. It is new and unsuggested in the art to apply heat in an effort to reduce body temperature. The invention effects the desired lowering of body temperature by the method of raising the temperature of the hypothalamus, a brain structure situated in humans just above the pituitary gland responsible for temperature regulation, by warming a nasal passage, or a sinus, such as the sphenoid sinus that is nearest to the hypothalamus, or by direct warming of the hypothalamus, or a combination of these.
