摘要：
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.
