Implantable pulse generator that generates spinal cord stimulation signals for a human body

An implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body, comprising:

• a signal generator for generating the stimulation signals, said signal generator comprising:
• an arbitrator;
• a high frequency generator;
• control registers storing stimulation signal parameters for a plurality of channels with each channel capable of being associated with at least two electrodes among a plurality of electrodes, each channel representing a stimulation signal pattern of the associated electrodes;
• a timing generator adapted to generate timing signals representing stimulation signals for the plurality of channels according to the stored signal parameters;
• an electrode driver for each electrode, and adapted to adjust an amplitude of the timing signals from the timing generator according to the stored signal parameters and output an output current corresponding to the adjusted signals for transmission to the associated electrode so as to enable independent control of the amplitude of the stimulation signal for each said channel,
• wherein a register bus is configured to allow electronic communication between the arbitrator, the high frequency generator, the timing generator, and the electrode driver for each electrode;
• and
• a treatment control module configured to instruct the signal generator to generate the stimulation signals while a microcontroller electrically connected to the signal generator is in standby mode.
