  • System and method for controlling patient temperature
    Patent number: 6530945
    Abstract: A controller for a heat exchanger that heats and cools saline flowing through a closed loop heat exchange catheter cools the saline to achieve a target temperature, and then immediately upon reaching target temperature heats the saline. Upon detection of, e.g., a slight patient temperature rise, the controller cools the saline again, with the control loop continuing to tightly control patient temperature in a narrow band around the target temperature.

  • Cooling system for therapeutic catheter
    Patent number: 6436130
    Abstract: A heat exchanger to remove heat from coolant in a closed circuit cooling catheter includes two heat exchange stages. Each stage includes a heat exchange element, such as a group of hollow fibers, and a TEC array juxtaposed with the heat exchange element to remove heat from the element. The elements are in fluid series with each other and are separated from each other by a thermal barrier. A thermal interface can be provided between each element and its TEC array. In one embodiment, the thermal interface is a gel layer. In another embodiment, the thermal interface is an ethylene glycol bath.

  • Temperature probe with dual sensors
    Publication number: 20020026227
    Abstract: A temperature probe having dual temperature elements is connected to a cooling catheter controller to provide redundancy in temperature feedback to the controller, namely, to provide both a control temperature feedback signal and an alarm temperature feedback signal to the controller.

  • Temperature probe and interconnect cable for hypothermia catheter temperature feedback
    Patent number: 6290717
    Abstract: A disposable esophageal probe having dual temperature elements is connected to a cooling catheter controller via a reusable interconnect line to provide redundancy in temperature feedback to the controller, namely, to provide both a control temperature feedback signal and an alarm temperature feedback signal to the controller.
