Abstract: Devices and methods for controlling the operation of endovascular heat exchange devices and/or body surface heat exchange devices such as blankets.

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: Closed loop heat exchange catheter systems and methods for preparing and using such systems wherein a reservoir or fluid bag is connected to the catheter system and used for at least priming of the system with a heat exchange fluid.

Abstract: The present invention provides a method and apparatus for controlling the internal body temperature of a patient. According to the present invention, a catheter is inserted through an incision into a large blood vessel of a patient. By selectively heating or cooling a portion of the catheter lying within the blood vessel, heat may be transferred to or from blood flowing within the vessel and the patient's body temperature may thereby be increased or decreased as desired. The invention will find use in treating undesirable conditions of hypothermia and hyperthermia, or for inducing a condition of artificial hypothermia when desired. The method and system further provide for the cooling of initially hypothermic patients whose blood or body temperature has been warmed above the desired target level and the warming of initially hyperthermic patients whose blood or body temperature has been cooled below the desired target temperature.

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.
