How does it work?
The technology behind this implant works by stimulating the vagus nerve. The vagus nerve is a collection of nerve fibers that run from the brain to the abdomen and various organs, such as the gut, lungs, spleen, heart relaying messages back and forth between the brain and these parts of the body.
Specialists can implant this pacemaker-like device in the left collarbone and connect wires from the implant to the vagus nerve in the neck. This technology has already been used to treat a number of other disorders and diseases, ranging from epilepsy to depression, when other treatments have not been successful.
