Implantable head mounted neurostimulation system for head pain
First Claim
1. A head-mounted neurostimulator, comprising:
- an implantable pulse generator (IPG), the IPG having;
a first body including circuitry for generating stimulating signals and disposed in a first plane,a second body including a coil for inductively receiving power and disposed in a second plane so that the first plane is adjacent and non-overlapping the second plane, the coil in the second body being interfaced with the circuitry in the first body, anda battery for being charged by the circuitry with inductive power received by the coil;
a first lead having a first lead body interfaced with the circuitry in the first body on a proximal end and having a first array of electrodes exposed to the exterior of the first lead body proximate a distal end thereof, each of the electrodes conductively and separately interfaced to the circuitry in the first body through the first lead body to receive simulating signals therefrom;
a second lead having a second lead body interfaced with the circuitry in the first body on a proximal end and having a second array of electrodes exposed to the exterior of the second lead body proximate a distal end thereof, each of the electrodes conductively and separately interfaced to the circuitry in the first body through the second lead body to receive simulating signals therefrom; and
a coating disposed over the first and second bodies and at least a portion of the first and second leads on the proximal ends thereof to form a unibody construction;
wherein the circuitry in the first body is operable to drive the electrodes in the first and second arrays simultaneously, such that select ones of the electrodes can be driven to provide stimulating signals.

Abstract
An implantable head-mounted 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, which may be sub-divided 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 surface metal electrodes. The IPG may include a rechargeable battery, an antenna, and an application specific integrated circuit. The IPG may be capable of functional connection with an external radiofrequency unit for purposes that may include recharging, diagnostic evaluation, and programming.
