IMPLANTABLE HEAD LOCATED RADIOFREQUENCY COUPLED NEUROSTIMULATION SYSTEM FOR HEAD PAIN

摘要

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.

1. A system for driving an implantable neurostimulator lead having a plurality of electrodes disposed in at least one array, comprising:
an implantable pulse generator (IPG), including:
an electrode driver for driving the electrodes,a load system for determining load requirements of the IPG,an IPG power coupler for receiving power across a dermis layer for interface of the power with the electrode driver, andan IPG communication system for transmitting the load determined requirement of the IPG across the dermis layer; and an external unit including:
an external variable power generator,an external power coupler for coupling power across the dermis layer to the IPG power coupler,an external communication system for receiving from the IPG communication system the determined load requirements, anda controller for varying the power level of the variable power generator as a function of the received determined load requirements of the IPG.
