C2 CryoBalloon Controller, REF: FG-1017, with Controller Software v1.18.258 The C2 CryoBalloon Ablation System is intended to be used as a cryosurgical tool in the field of general surgery, specifically for endoscopic application and the ablation of dysplastic Barrett s Esophagus.

The Controller does not detect overpressure in the balloon during the application of non-dosing puffs of Nitrous Oxide, which can contribute to balloon over pressurization, if the intended vent lumen of the catheter is significantly occluded to prevent relieving balloon pressure due to a kinked catheter condition.If a patient is exposed to higher than physiologic pressures, adverse events such as perforation or mucosal laceration may occur.
