"For this study, we wanted to get an initial assessment of whether blocking the vagus nerve electrically could cause obese patients to feel full after a normal-sized meal. Patients were not put on any restricted diets or given counseling that typically accompanies gastric banding or bypass. We wanted to determine how much weight loss could be attributed to the device alone."
— Michael Camilleri, MD, a gastroenterologist at the Mayo Clinic (Rochester, Minnesota) who helped design a study to test a new implantable device-based therapy developed by EnterMedics (St. Paul, Minnesota) called VBLOC, or vagal blocking therapy, that is being touted as a safer alternative to bariatric procedures, "VBLOC seen safer weight-loss alternative than surgeries," pp. 1, 6.
