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.
