System and method using the rectal mucosal membrane for inducing hypothermia and warming

a rectal mucosal membrane and system technology, applied in the field of system and method for inducing hypothermia and warming the body, can solve the problems of inconvenient cooling by cold blankets and dressings, inability to achieve and maintain hypothermia of the central nervous system, and inability to achieve and maintain hypothermia on the surface, etc., to achieve efficient and effective cooling, prolong the reversal of cranial structures, and increase intraabdominal pressure

Abstract

A system and method for cooling and warming the central nervous system of a patient comprises a delivery tube with one of the ends couplable to a supply of fluid. A head structure is coupled to the other end of the delivery tube and cooling or warming fluid is directed through the tube to the head structure. The head structure is configured to be placed within the rectal cavity of a patient such that either a contact surface on the head structure or the fluid itself directly contacts a portion of the rectal mucosal membrane. A means for reversing the vertebral venous flow of blood through Batson's plexus supplies cooled or warmed blood directly to the vertebral structures. Unique methods of utilizing the system to selectively cool and warm the central nervous system structures of a patient are set forth herein.

Description

RELATED APPLICATION

[0001] This application is a Divisional of U. S. patent application Ser. No. 10 / 224,023, entitled “System and Method Using the Rectal Mucosal Membrane for Inducing Hypothermia and Warming,” and filed Aug. 20, 2002, the disclosure of which is hereby incorporated herein by reference in its entirety.FIELD THE INVENTION

[0002] The present invention relates generally to a system and method for cooling and warming the body and specifically relates to a system and method for selectively inducing hypothermia or warming in the central nervous system. BACKGROUND OF THE INVENTION

[0003] Hypothermia, which is the condition of lowered normal body temperature in a warm blooded animal, has been used therapeutically for the treatment of human brain injury, spinal cord injury, and spinal cord ischemia for many years. Therapeutic hypothermia is used as a neural protectant in situations where there is central nervous system ischemia, trauma, or hypoxia. Such situations can occur fr...
