Abstract
An implantable peripheral neurostimulation lead for head pain is adapted for implantation in the head for the therapeutic purpose of treating chronic head and/or face pain. The lead may include a lead body, a plurality of internal electrically conducting metal wires individually connecting to a proximal surface contact and a distal surface electrode; a distal extended metal surface electrode array; and a proximal in-line connector. The lead may be operable to provide medically acceptable therapeutic neurostimulation to multiple regions of the head, including the frontal, parietal, and occipital regions of the head simultaneously. The lead may include a supraorbital electrode array with electrodes of 3 to 5 mm in length spaced apart at 4 to 6 mm intervals. The lead may also include a temporal electrode array with electrodes of 4 to 6 mm in length spaced apart at 8 to 12 mm intervals.
