Attune Medical’s ensoETM modulates and controls patient temperature through a single-use silicone tube inserted into the esophagus, similar to a standard gastric tube, and connected to an external heat exchange unit. Positioned at the core, next to the heart and great vessels, water circulates inside the closed-loop system to efficiently warm or cool a patient. Unlike surface warming devices, the Enso’s internal placement won’t impede patient access during surgery, and allows gastric decompression and administration of fluids and medications. The ensoETM works with existing heat exchangers and can be rapidly placed by most trained health care professionals. The ensoETM is the only device cleared for use in the esophagus for whole-body temperature modulation.
