  • Publication number: 20170112662
    Abstract: An intravenous heat exchange catheter and/or an external cooling pad/bladder can be used to maintain hypothermia in, e.g., a cardiac arrest patient, but to accelerate the cooling process the patient first can be infused with cold saline before the opportunity arises to connect the catheter or pad to the patient.
    Type: Application

  • Patent number: 8888729
    Abstract: A catheter is adapted to exchange heat with a body fluid, such as blood, flowing in a body conduit, such as a blood vessel. The catheter includes a shaft with a heat exchange region disposed at its distal end. This region may include hollow fibers which are adapted to receive a remotely cooled heat exchange fluid preferably flowing in a direction counter to that of the body fluid. The hollow fibers enhance the surface area of contact, as well as the mixing of both the heat exchange fluid and the body fluid. The catheter can be positioned to produce hypothermia in a selective area of the body or alternatively positioned to systemically cool the entire body system.

  • Patent number: 7101388
    Abstract: A system for exchanging heat with the body of a patient for cooling or warming the patient provides for automatic temperature control in accordance with the monitored temperature of the patient. The system comprises a temperature control module and temperature probes for making body core temperature measurements. The body core temperature measurements are used to control the temperature of fluid circulating within the fluid circuit.
