Dr. Deirdre Stewart, Ph.D., Set to Present New Device for Detecting Reflux at Annual SLEEP 2006 APSS Meeting

Salt Lake City, UT - June 15, 2006

Dr. Deirdre Stewart, Vice President of Clinical Affairs at Restech, will present information on a new patient-friendly device for detecting gastric reflux in the airway and its application in sleep medicine on Sunday, June 18 th at 11:30 a.m. at the Association of Polysomnographic Technologists meeting, a segment of the SLEEP 2006 Associated Professional Sleep Societies (APSS) event.

Restech's Dx-pH Measurement System™ detects aerosolized reflux in the upper airway, known as laryngopharyngeal reflux (LPR). The miniature 1.5mm diameter catheter is placed trans-nasally and is positioned behind the soft palate, which allows patients to eat, drink and sleep comfortably, thereby fostering realistic study results. The probe tip's sensor is designed in a revolutionary teardrop shape, which unlike conventional catheters is resistant to becoming embedded in the mucosal wall.

The Restech "plug & play" Dx-Sleep Adapter™ allows sleep medicine professionals to track patients' airway pH events in real-time on their existing monitoring equipment. The system can be easily set up in a sleep clinic or physician's office.

Gastric reflux, respiratory disease and sleep disordered breathing are rapidly growing health concerns worldwide. Clinical studies have found that gastric events in the airway are associated with and known to exacerbate serious respiratory disorders such as asthma, chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA). OSA affects approximately 20 million Americans and significant reflux occurs in at least half of this population. Yet, a suitable sensor has been unavailable to identify such events until now.

Ross Tsukashima, Director of Product Development at Restech, will complement the presentation with his expertise in physiologic pH measurement. Mr. Tsukashima has authored nine patents and was awarded a 2002 Silver Medal in Business Week's "Industrial Design Excellence Awards."

Restech is a privately held corporation specializing in the development of innovative medical devices. For more information on the Dx-pH Measurement System, or to arrange an interview with Dr. Stewart, call Debra Krahel or Wal Flicker at (800) 352-1512 or visit http://www.restech-corp.com.
