Abstract
An implantable head-mounted, radiofrequency (RF) coupled, unibody peripheral neurostimulation system is provided for implantation in the head for the purpose of treating chronic head pain, including migraine. The system may include an implantable pulse generator (IPG) from which multiple stimulating leads may extend sufficient to allow for adequate stimulation over multiple regions of the head, preferably including the frontal, parietal and occipital regions. A lead may include an extended body, along which may be disposed a plurality of surface metal electrodes (SME), which may be subdivided into a plurality of electrode arrays. A plurality of internal metal wires may run a portion of its length and connect the IPG's internal circuit to the SME. The IPG may include an RF receiver coil and an application specific integrated circuit. The IPG may be capable of functional connection to an external RF unit for purposes that may include power, diagnostics, and programming.
