Abstract
A heat transfer device has first and second elongated, articulated segments, each having a turbulence-inducing exterior surface. A flexible joint connects the first and second elongated, articulated segments. An inner coaxial lumen is disposed within the first and second elongated, articulated segments. The inner coaxial lumen is capable of transporting a pressurized working fluid to a distal end of the first elongated, articulated segment.

31. A method for providing whole-body cooling of a patient, the method comprising:
-
providing a catheter with a conductive heat transfer element at a distal end thereof;
inserting the catheter and heat transfer element into the vascular system of the patient;
utilizing the heat transfer element to modify the temperature of blood which flows in heat exchange proximity to the heat transfer element, such that said modification of the blood will accomplish whole-body cooling of the patient. - View Dependent Claims (32, 33, 34, 35, 36)
