Procedure
The C2 CryoBalloon Ablation System delivers precise, controlled cryoablation for endoscopic treatment of Barrett’s esophagus with dysplasia and gastric antral vascular ectasia (GAVE). Standard and pear-shaped catheter designs reach tubular structures, the gastroesophageal junction, and lesions big and small. Physicians can selectively target and ablate diseased tissue and spare healthy tissue, using nitrous oxide (N2O) to cryogenically freeze and cause necrosis to the target tissue for treatment.
The 180° catheter effectively treats long-segment Barrett’s esophagus and maintains the flexibility, accuracy, and visibility of our focal catheter.

For precise, targeted, short-segment Barrett’s esophagus, the C2 CryoBalloon treats tissue at a cellular level.

Cryoablation causes minimal structural damage to the treated tissue, ultimately preserving the collagen matrix structure.4 Cryoablation has a low adverse-event rate, including strictures and bleeding.5 Patients also report significantly less post-procedural pain and need for narcotic medication compared with radiofrequency ablation.5-7

The C2 CryoBalloon Ablation System is a Merit Medical product used for the endoscopic treatment of Barrett’s esophagus with dysplasia and GAVE. It delivers precise, controlled cryoablation using N2O to selectively target and ablate diseased tissue while sparing healthy tissue. Two catheter designs are available—the focal catheter for short-segment Barrett’s esophagus and the 180° catheter for long-segment Barrett’s esophagus.
The C2 CryoBalloon Ablation System is indicated for the endoscopic treatment of Barrett’s esophagus with dysplasia, including both low-grade and high-grade dysplasia, and GAVE. Refer to the full Instructions for Use for complete indications, contraindications, warnings, and precautions.
Cryoablation causes minimal structural damage to the treated tissue, ultimately preserving the collagen matrix structure,4 and has a low adverse-event rate, including strictures and bleeding.5 Patients also report significantly less post-procedural pain and need for narcotic medication compared with radiofrequency ablation.5-7 A comparative study7 found that cryoablation treatment for Barrett’s esophagus resulted in greater patient-reported reduction of post-treatment analgesic use compared with heat-based radiofrequency ablation treatment.
The C2 CryoBalloon is available in two catheter designs. The focal catheter (available in pear and standard shapes) is designed for precise, targeted treatment of short-segment Barrett’s esophagus. It treats tissue at a cellular level, and the pear-shaped design allows it to reach the gastroesophageal junction and irregular lesions. The 180° catheter, available in standard (FG-1055) and pear (FG-1056) configurations, effectively treats long-segment Barrett’s esophagus while maintaining the flexibility, accuracy, and visibility of the focal catheter.
