An indwelling heat exchange catheter with integrated temperature sensor includes a catheter tube. A closed loop heat exchanger extends from the catheter tube. A temperature sensor can be integrally formed with the catheter tube such that it is insulated from the closed loop heat exchanger. The indwelling heat exchange catheter can further include a guide-wire tube that extends from the catheter tube and in such a case, the temperature sensor can be affixed to the guide-wire tube. Alternatively, a wire can extend through the catheter tube and the temperature sensor can be affixed to the wire.

Intravascular heat exchange catheter with temperature sensor

A heat exchange catheter has a catheter body with an inflow lumen, an outflow lumen, and an infusion lumen. A first heat exchange balloon helically wraps around at least a portion of the catheter body in fluid communication with the inflow lumen. A second heat exchange balloon helically wraps around at least a portion of the catheter body in fluid communication with the outflow lumen. The first and second balloons form a gap there between to facilitate infusion of fluid into the blood stream of the patient via an infusion port formed within the gap.
