Name: EnteroMedics

Location: St. Paul, MN

Procedure: EnteroMedics has developed the Maestro system that includes a pacemaker-like device that is implanted under the skin. Leads extend out from that device and transmit mild electrical signals to the vagus nerve, which controls hunger and the feeling of being full.

The neuromodulation therapy - called vBloc - works by tricking the brain into thinking that the person is not hungry. It does so by blocking those signals to and from the vagus nerve.

FDA Status: Approved in January
