C2 CryoBalloon™

C2 CryoBalloon™ – Exceeding expectations1), 2)
A vital part of your comprehensive offering for patients with Barrett’s esophagus with dysplasia

Ready to ablate a wide range2)

Highly safe and effective in both naïve and refractory patients with Barrett’s esophagus. New catheter designs reach tubular structures, gastroesophageal junction (GEJ), and big and small lesions.

This device changes how you see Barrett’s esophagus 2)

C2 CryoBalloon Pear Catheter at the GEJ C2 CryoBalloon Focal Standard Catheter ablating naïve tissue
"With C2, I can offer my patients the latest and most effective treatment options and develop a more comprehensive Barrett’s center"
Harshit S. Khara, MD. FACG, FASGE Clinical Associate Professor of Medicine, Director of Endoscopy, Geisinger Medical Center


Enhanced visualization2), 4), 5)

Transparent compliant balloon pushes tissue flat for better apposition and controlled therapeutic delivery. With advanced rotational and translational capabilities, physicians can selectively target and ablate diseased areas while sparing healthy tissue. Intuitive controls give physicians total control of balloon inflation, deflation, diffuser positioning, and ablation.


Generating a robust clinical data pipeline in Barrett’s esophagus and beyond
Highly effective and durable response through 2 years2), 3)



"The C2 CryoBalloon is an endoscopic technology which helps freeze pre-cancerous cells within Barrett’s esophagus to reduce the risk of developing cancer. And there’s a lot of data to support that this is a highly effective treatment in reducing that risk."
Dr. Vinay Sehgal, Consultant gastroenterologist and interventional endoscopist at University College Hospital London, UK



Patients experienced less post-procedure pain and need for narcotic medication2), 4)

  • Peak pain was lower after CryoBalloon ablation (median VAS 2 vs. 4, P < .01)
  • Duration of pain was shorter after CryoBalloon ablation (median 2 vs. 4 days, P < .01)
  • Mild pain was reported by 27% of patients immediately after cryoablation and by 14% after 2 days2)
Cryoablation is significantly less painful than RFA4)

"I also noticed that on the patients we have treated, they have less pain during the procedure, so I recognize that they don’t need so much painkillers during the procedure and after the procedure."
Dr. Khanh Do-Cong Pham, Consultant endoscopist and gastroenterologist at Haukeland University Hospital, Bergen, Norway


Practice integration made easy with simplicity and speed2), 3), 8)
