The Rapid AV Catheter is designed for use in procedures requiring active venting, such as spray cryotherapy in gastrointestinal (GI) endoscopy cases.
The Rapid AV Catheter Technology
The Rapid AV catheter is primarily used in gastrointestinal procedures that require active venting to ablate benign disease and malignancies such as esophageal cancer. The catheter is specially designed to deliver cold LN2 at -196°C to cause a fast freeze and allow for a slow thaw of the tissue. This fast freeze and slow thaw cycle effectively kills tissue by causing instant and delayed cell death for a more effective treatment of diseased cells of the tissue.
How the Rapid AV Catheter and Active Venting Cryotherapy Works
The Rapid AV catheter is designed for the delivery of spray cryotherapy treatment for Barrett’s esophagus and spray cryotherapy for esophageal cancer – utilizing an active venting method. This specially designed catheter features decreased time to frost by 50%, minimizing overall ablation time.
Examples of additional benign and malignant applications include:

Case Studies
Barrett’s Esophagus with High Grade Dysplasia:
In a recent study showing long-term results over five years, 93% of patients achieved complete eradication of high-grade dysplasia (CE-HGD). 88% achieved complete eradication of dysplasia (CE-D) and 75% achieve complete eradication of intestinal metaplasia (CE-IM).1
Relief of Dysphagia in Advanced Esophageal Cancer:
In a multicenter trial of 49 patients with inoperable esophageal cancer, liquid nitrogen cryotherapy showed statistically significant improvement in patients’ dysphagia (difficulty swallowing) taking them from an MDS (Mean Dysphagia Score) of 2.4 to 1.7 on the 4-point Likert scale. Further, the study suggests that liquid nitrogen cryotherapy may be safe and effective for dysphagia palliation in inoperable esophageal cancer.2
