Abstract
A catheter and method are provided for modifying a temperature of a patient. The catheter includes a heat transfer element ('HTE') having surface irregularities shaped to create turbulence in a surrounding fluid. The catheter also includes a supply catheter to deliver a working fluid to an interior of the heat transfer element and a return catheter to return a working fluid from the HTE. A guidewire lumen is provided to receive a guidewire. The guidewire may have a temperature-monitoring device disposed at its distal tip from which feedback may be provided to control the temperature of a source of the working fluid.
