A system is provided for driving an implantable neurostimulator lead, the lead having an associated plurality of electrodes disposed in at least one array on the lead. The system comprises an implantable pulse generator (IPG), the IPG including an electrode driver, a load system for determining load requirements, an IPG power coupler, and an IPG communication system. The system also includes an external unit, which includes an external variable power generator, an external power coupler, an external communication system, and a controller for varying the power level of the variable power generator.

Implantable head located radiofrequency coupled neurostimulation system for head pain

A system for transferring power to, and communicating with, at least one body-implantable active device includes an external power transfer system associated with an external device disposed outside of a body, operable to transfer power through a dermis layer to each body-implantable active device, and communicate data to and from each body-implantable active device, and also includes a power receiving system associated with each body-implantable active device, operable to receive power transferred from the external power transfer system, and communicate data to and from the external power transfer system. The body-implantable active device may include an implantable neurostimulation system.

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.

A method is provided for controlling power delivery from an external power transfer system (EPTS) to at least one implantable neurostimulator system (INS). The method comprises driving a first transmit coil within the EPTS using a transmit coil driver circuit, receiving, using a receive coil, power transferred from the first transmit coil, coupling the received power to a regulator circuit, monitoring the regulator circuit, communicating a message to the EPTS using a back telemetry circuit, receiving the message, and adjusting the transmit coil driver circuit.
