Covidien (NYSE: COV), a leading global provider of healthcare products, announced the expansion of its portfolio of radiofrequency ablation (RFA) catheters with the launch of the Barrx™ Channel RFA Endoscopic Catheter for treating Barrett’s esophagus and certain gastrointestinal bleeding disorders 1. Left untreated, Barrett’s esophagus, a precancerous condition of the esophageal lining, can lead to life-threatening cancer of the esophagus. The Barrx line of RFA catheters is based on Covidien’s proprietary technology that carefully controls the amount of RF energy delivered to remove diseased tissue, thereby allowing the growth of healthy tissue. Endoscopic surgeons and gastroenterologists can shorten procedure time with the new Channel RFA device, as this patient-centric design allows for fewer endoscope introductions and removals (compared to other Barrx catheters). The innovative technology in the Channel catheter enables a 7.5mm wide electrode to easily pass through a 2.8mm diameter endoscope working channel. “Covidien continues to offer patients and physicians a solution to address Barrett’s esophagus,” said Vafa Jamali, Vice President and General Manager, GI Solutions, Covidien. “The newest addition to the Barrx portfolio is designed to simplify the procedure by delivering our proven RF technology through the working channel of the endoscope.” Other features and benefits of the new device include a transparent ablation electrode for enhanced visualization and a unique rotatable shaft design that provides additional control and maneuverability. The Barrx Channel RFA Endoscopic Catheter is available in the United States and Europe.
