 The aim of this prospective, interventional study is to assess the feasibility and safety of the Esophageal Cooling Device in patients from suffering from traumatic brain injury who the treating physician is treating with targeted temperature management. Comparison of outcomes will be made to historical controls. The primary outcome is the feasibility of inducing, maintaining, and rewarming patients from targeted temperature management using the Esophageal Cooling Device cooling rate, rewarming rate, and the percent of time within goal temperature during the goal-temperature maintenance period. Evaluation of adverse events including cardiac arrhythmias, severe bradycardia, myocardial infarctionre-infarction, dysphagia, odynophagia, aspiration pneumonia, non-aspiration pneumonia, reflux, esophageal injury, and esophagitis will be closely monitored during the whole period of targeted temperature management secondary endpoint.
