Implantable head located radiofrequency coupled neurostimulation system for head pain
First Claim
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 current limiting current regulator for limiting the current to the IPG,a load system for determining a minimum load requirement of the IPG to provide the necessary power to the current regulator,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 determined minimum load 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 minimum load requirement of the IPG, anda controller for varying the power level of the variable power generator as a function of the received determined minimum load requirement of the IPG.
