Abstract: Methods and apparatus for treating or deterring injuries to or disorders of the brain or spinal cord of a subject. A heat exchange catheter device is inserted into the subject's body and used to cause heating or cooling the subject's cerebrospinal fluid. In some embodiments, the heat exchanger may be positioned within the subject's vasculature so as to heat or cool the flowing blood, thereby resulting in heating or cooling of the cerebrobpinal fluid.

Abstract: Methods and apparatus for temperature modification of selected body regions including an induced state of local hypothermia of the brain region for neuroprotection. A heat exchange catheter is provided with heat transfer fins projecting or extending outward from the catheter which may be inserted into selected blood vessels or body regions to transfer heat with blood or fluid in the selected blood vessels or body regions. Another aspect of the invention further provides methods and apparatus for controlling the internal body temperature of a patient. By selectively heating or cooling a portion of the catheter lying within a blood vessel, heat may be transferred to or from blood flowing within the vessel to increase or decrease whole body temperature or the temperature of a target region. Feed back from temperature sensors located within the patient's body allow for control of the heat transfer from the catheter to automatically control the temperature of the patient or of the target region within the patient.
