Abstract: Methods and apparatus are provided for heating or cooling a patient's whole body or a selected portion of a patient's body. In one embodiment, the method begins by inserting a catheter having a dual balloon system into the large intestine of a patient. A heated or chilled liquid is conducted through a supply tube of the catheter and into the inner balloon. The liquid is evacuated from the inner balloon through a return lumen of the catheter. The outer balloon conducts heat transfer between the patient's tissues and the inner balloon, and further provides a degree of safety against rupture of the inner balloon.

Abstract: A guidable catheter for heating or cooling fluid in a feeding vessel in a vasculature of a patient includes a heat transfer element having exterior surface irregularities to create turbulence in a surrounding fluid. A supply catheter delivers a working fluid to an interior of the heat transfer element, and a return catheter returns a working fluid from the interior of the heat transfer element. A guidewire tube is provided adjacent one of the supply catheter or the return catheter and runs substantially parallel to the axis of the guidable catheter to receive a guidewire disposed within the guidewire tube. A temperature-monitoring device is disposed at the distal tip of the guidewire. Feedback is provided to control the temperature of a source of working fluid.

Abstract: An endovascular heat transfer device which can have a smooth exterior surface, or a surface with ridges and grooves. The device can have a plurality of elongated, articulated segments, with each having such a surface. A flexible joint connects adjacent elongated, articulated segments. The flexible joints can be bellows or flexible tubes. An inner lumen is disposed within the heat transfer segments. The inner lumen is capable of transporting a pressurized working fluid to a distal end of the heat transfer element.
