Abstract
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.
