Remote control of power or polarity selection for a neural stimulator
First Claim
1. A system for modulating neural tissue in a patient comprising:
- an implantable neural stimulator comprising one or more electrodes, at least one antenna and an electrode interface;
a radio-frequency (RF) pulse generator module comprising an antenna module configured to send an input signal to the at least one antenna in the implantable neural stimulator through electrical radiative coupling, the input signal containing electrical energy and polarity assignment information that designates polarity assignments of the one or more electrodes in the implantable neural stimulator, wherein the antenna module is further configured transmit to the implantable neural stimulator a first input signal containing the electrical energy and a second input signal containing the polarity assignment information, wherein the first input signal has a different carrier frequency than the second input signal; and
wherein the implantable neural stimulator is configured to;
control the electrode interface such that the one or more electrodes have the polarity assignments designated by the polarity assignment information,create one or more electrical pulses suitable for modulation of neural tissue using the electrical energy contained in the input signal, andsupply the electrical pulses to the one or more electrodes through the electrode interface such that the one or more electrodes apply the electrical pulses to the neural tissue with the polarity assignments designated by the polarity assignment information.
