The EnsoETM is a non-sterile multi-lumen silicone tube placed in the esophagus for the purpose of cooling or warming a patient while simultaneously allowing gastric decompression and drainage. Modulation and control of the patient's temperature is achieved by connecting the EnsoETM to an external heat exchanger. Two lumens connect to the external heat exchanger, while a third central lumen provides stomach access for connection to a fluid collection device with low intermittent suction for gastric decompression. The EnsoETM is made of standard medical-grade silicone. It is a single-use, disposable, non-implantable device with an intended duration of use of 72 hours or less. Distilled water circulates within the EnsoETM just like a water blanket.
