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.
