FDA Approves Implantable Vagus Nerve Disruptor For Weight Loss 168
The L.A. Times reports that for the first time since 2007, the FDA has approved a weight loss device (as opposed to a weight-loss drug), an implantable device called the Maestro Rechargeable System. Using electrical leads implanted just above the stomach and a regulator carried under the skin near the ribcage, the device suppresses signals carried by the vagus nerve. ... The device adopts a variant of a "neuromodulation" technique long used in the treatment of epilepsy: by applying intermittent bursts of electrical current to the vagus nerve, it disrupts the signals that prompt the stomach to relax, expand and prepare for an influx of food. ... The FDA approved the use of the device in adult patients with a body mass index, or BMI, between 35 and 45, who have at least one other obesity-related condition, such as type 2 diabetes.
