Dr. Gregory Wiener to Present Data on Use of a New Sensitive System for Detecting Gastric Reflux in the Airway

Los Angeles,California, USA– May 22, 2006

Dr. Gregory Wiener will be presenting data on a new sensitive and patient-friendly device for detecting liquid and aerosolized supraesophageal gastric reflux (SEGR) events in the oropharynx at this week's international Digestive Disease Week conference in Los Angeles.

Clinical and animal studies have documented the association of the deleterious effects of acidic and weakly acidic events in the airway associated with widespread respiratory disorders such as asthma, Chronic Obstructive Pulmonary Disease (COPD) and sleep apnea. Identification of such events in the upper airway has evaded understanding due to the lack of a suitable and reliable sensor. Dr. Wiener will present data on the utility of the Restech Dx p-H Measurement System™ for this application. The Restech system uses a 1.5mm diameter nasopharyngeal catheter placed in the oropharynx behind the soft palate, a position that presents minimal discomfort to the patient and allows simple visual placement by the physician. It uses wireless telemetry to transmit the p H data from the catheter to a pocket-sized data recorder, further enhancing patient comfort.

In addition to Dr Wiener's talk, Restech will be holding a meeting of its Scientific Advisory Board, headed by Tom DeMeester, MD, Chair of Surgery, USC Keck School of Medicine. Other members of the Scientific Advisory Board include Michael Vaezi, MD PhD, Professor of Medicine, GI Clinical Director at Vanderbilt University, Greg Postma, MD, Professor and Director of the Medical College of Georgia Center for Voice and Swallowing Disorders, and George Triadafilopoulos, MD, Clinical Professor of Medicine, Division of Gastroenterology and Hepatology at Stanford University.

Dr. Wiener will be presenting at 8:30 a.m. on Wednesday, May 24, 2006 in Room 403B at the Los Angeles Convention Center. The Restech product display is located at booth 2459 in the Exhibit Hall.
