EnteroMedics Inc., (NASDAQ: ETRM), the developer of medical devices using neuroblocking technology to treat obesity, its associated co-morbidities, and other gastrointestinal disorders, announced today that it has received CE Mark approval of VBLOC™ Therapy delivered via the Maestro™ System for the treatment of obesity. The Maestro System is the first to treat obesity using neuroblocking technology and represents a less invasive alternative to existing surgical weight loss procedures, which alter digestive system anatomy, lifestyle and food choices and may present significant risks.

"Obesity is a growing epidemic worldwide," said President and CEO Mark B. Knudson, Ph.D. "VBLOC Therapy is a treatment innovation that offers individuals the promise of significant weight loss without having to accept nutritional, lifestyle and safety compromises. CE Mark approval represents a major milestone for EnteroMedics and is the first step in our global commercialization strategy."

CE Mark approval gives EnteroMedics the ability to market the Maestro System to countries of the European Economic Area. VBLOC Therapy is undergoing clinical testing in the United States and Australia in a pivotal trial known as the EMPOWER study. Provided a positive outcome from the study, EnteroMedics will use data from the EMPOWER trial to support a premarket approval (PMA) application for the Maestro System, which it expects to submit to the U.S. Food and Drug Administration in late 2009.

About VBLOC Therapy

EnteroMedics developed VBLOC™ vagal blocking therapy to offer bariatric surgeons and their patients a less invasive alternative to existing surgical weight loss procedures that may present significant risks and alter digestive system anatomy, lifestyle and food choices. VBLOC Therapy is delivered via the Maestro™ System through laparoscopically implanted leads to intermittently block the vagus nerves using high-frequency, low-energy electrical impulses. VBLOC Therapy is designed to target the multiple digestive functions under control of the vagus nerves and to affect the perception of hunger and fullness. Preliminary results from the feasibility study conducted outside the U.S., which includes 38 patients, indicate that the Maestro System may provide durable and ongoing weight-loss for people with obesity. Follow up data show excess weight loss, or EWL, of 37.6% in 9 patients at 18 months of VBLOC Therapy and 28.1% in 17 patients at 12 months of therapy. To date, no deaths or unanticipated adverse device events have been reported.
