"Barrett's sufferers are at increased risk for developing a dangerous type of cancer called esophageal adenocarcinoma, currently one of the fastest growing cancers in the United States," said Kathy Conte, managing director of life sciences at Hercules. "BARRX Medical's new product, the HALO360 System(TM), offers physicians a fast, effective, minimally invasive tool to treat precancerous conditions of the esophagus, through the use of radiofrequency (RF) ablation therapy. We are delighted to be an equity investor in this life-saving technology."

The HALO360 System enables physicians to remove the thin layer of esophageal lining containing Barrett's esophagus cells before it has a chance to develop into cancer, just as they would with any other precancerous conditions found in the body. The ability to safely and effective remove Barrett's esophagus may reduce the need for life-long endoscopic surveillance, ease patient anxiety about living with a precancerous condition, and possibly reduce the number of patients who eventually develop esophageal adenocarcinoma.
