The Esophageal Cooling Device by Advanced Cooling Therapy is designed to modulate and control patient temperature through a single use, fully enclosed triple lumen system that is inserted into the esophagus. Recent studies have shown its efficacy in warming patients in the OR, particularly for preventing inadvertent perioperative hypothermia. Two lumens attach to existing temperature modulation equipment while a third lumen simultaneously allows gastric decompression and drainage. The ECD can be rapidly inserted by most trained health care professionals, in similar fashion to a standard gastric tube, and can be used to cool or warm patients in the operating room, recovery room, emergency room or ICU. No other products on the market are approved to use the esophageal environment for whole-body temperature modulation.
