Beating obesity: The new pacemaker which helps over-eaters

In January 2015, the US Food and Drug Administration approved a new kind of obesity therapy. Vbloc is a vagus nerve pacemaker developed by EnteroMedics, a company based in St Paul, Minnesota. It works by intermittently blocking vagal nerve signals between the brain and the stomach. The idea stems from the observation of weight loss among patients who had their vagus nerve cut just below the diaphragm, once a common treatment for duodenal ulcers, because it reduces acid secretion.
