The present invention encompasses a heat exchange catheter for indirect cooling of internal organs, particularly the heart. The heat exchange catheter is inserted into the esophagus and a cooled fluid is circulated within the catheter, cooling the esophagus, and by conduction, the heart. The heat exchange catheter or the invention may be rapidly deployed in the field and is particularly useful for preventing and reducing tissue damage caused by ischemia.
