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 in the esophagus, next to the heart and great vessels, water circulates inside the closed-loop system to efficiently warm or cool a patient. Unlike surface devices, the ensoETM’s internal placement won’t impede patient access during procedures in the OR, ER, ICU or electrophysiology lab for various temperature management applications. The ensoETM works with existing heat exchangers and is the only device cleared for use in the esophagus for patient temperature modulation.
