A non-sterile, battery-powered device designed to non-invasively stimulate nerves of the head/face to prevent or treat headaches (including migraine) and/or frontal sinus pain; it may also be used to treat insomnia. It is a patient worn or hand-held device which typically consists of one or more electrodes designed to be placed on the forehead or other parts of the face, and a pulse generator to provide the electric current. The device is typically used by a patient in the home and the therapy may be referred to as neurostimulation or transcutaneous electrical stimulation (TENS). This is a reusable device.
