ensoETM®

Protection. Freedom. Efficiency.
The ensoETM® system provides esophageal protection through proactive cooling during radiofrequency (RF) cardiac ablation.* Akin to a standard orogastric tube circulating chilled water, the ensoETM system has demonstrated a 100% per-protocol reduction in severe esophageal lesions,1 and a 14% absolute increase in freedom from atrial arrhythmia at one year.3 Additionally, the ensoETM system eliminates temperature alarms and stoppages associated with luminal esophageal temperature (LET) monitoring,4 resulting in a reduction in mean procedure time by 36–60 minutes.5,6 The ensoETM system has an FDA-granted indication to reduce the likelihood of ablation-related esophageal injury resulting from RF cardiac ablation procedures​.
