The truFreeze® Spray Cryotherapy ablation technology system is indicated for the treatment of esophageal and airway diseases, such as Barrett's esophagus and esophageal cancer, by delivering liquid nitrogen (LN2) at -196°C. LN2 is the coldest cryogen available and the only cryogen capable of ablating benign and malignant cells. Liquid nitrogen spray cryotherapy traps and flash-freezes water in cells causing cell death while preserving the extracellular matrix, promoting a rejuvenative healing response.
