Medtronic / Covidien Products / Gastrointestinal Radiofrequency Ablation Systems / Barrx™ Radiofrequency Ablation System

Overview

Progression can be deadly. Think beyond surveillance.

Barrx™ radiofrequency ablation system is designed to precisely eradicate the Barrett’s epithelium.1 Barrett's esophagus patients with low-grade dyplasia treated with RFA have a substantial reduction in progression compared to patients who undergo surveillance alone.2

The Barrx™ radiofrequency ablation system includes the Barrx™ flex RFA energy generator and a family of ablation catheters.

The power to make a difference​

Eradicate Barrett’s esophagus for patients with low-grade dysplasia and reduce the relative risk of disease progression to high-grade dysplasia and esophageal adenocarcinoma by up to 94% with the Barrx™ radiofrequency ablation system.2,3,7,†

Major GI societies endorse radiofrequency ablation in the treatment guidelines ​for Barrett’s esophagus. With demonstrated efficacy, safety,1 and support from leading institutions8,9 this technology allows you to act with confidence.

When risk of progression is high, proactively treat with the Barrx™ radiofrequency ablation system.

Think beyond surveillance​

Progression of Barrett’s esophagus to esophageal adenocarcinoma (EAC) can ​be deadly.10 Surveillance may not be enough for some patients.​

Clinical data has identified several risk factors that contribute to disease progression, including:​

  • Dysplasia2,3
  • Family history of Barrett’s esophagus or EAC​4
  • Long-segment disease​5
  • Smoking tobacco6

One generator. Multiple solutions.

The Barrx™ flex RFA energy generator is a bipolar radiofrequency generator that provides the flexibility to chose either the Barrx™ 360 express RFA balloon catheter for larger treatment areas or Barrx™ RFA focal catheters for smaller focal areas.

Our product portfolio 

Barrx™ flex RFA energy generator

The Barrx™ radiofrequency ablation system includes the Barrx™ flex RFA energy generator and a family of ablation catheters which are designed to control depth and uniformity of gastrointestinal (GI) tissue ablation.

Barrx™ 360 express RFA balloon catheter

The Barrx™ 360 express RFA balloon catheter features a self-adjusting ablation balloon that eliminates the sizing process.

Barrx™ RFA focal catheters

The Barrx™ RFA focal catheter enables physicians to provide primary treatment for short and intermediate length segments of non-circumferential Barrett's esophagus or provide secondary treatment after ablation with the Barrx™ 360 RFA balloon catheter (or other therapeutic devices).

Barrx™ channel RFA endoscopic catheter

The Barrx™ channel RFA endoscopic catheter delivers radiofrequency ablation, after being placed through the working channel of a flexible endoscope.

Barrx™ RFA accessories

Barrx™ accessories include endoscopic guidewires, cleaning caps, and a cart to hold ablation equipment.
