Amplitude Modulating Waveform Pattern Generation for Stimulation in an Implantable Pulse Generator

An implantable medical device (IMD) comprising:

• a pulse generator adapted for use with one or more electrode leads, wherein each electrode lead comprises a plurality of electrodes, wherein the pulse generator comprises:
• control circuitry configured to cause one or more pulses to be delivered at one or more of the plurality of electrodes,
• memory circuitry configured to store:
• a plurality of pulse programs, wherein each of the pulse programs specifies a pulse amplitude,
• a plurality of steering programs, wherein each of the steering programs specifies one or more of the plurality of electrodes to deliver the one or more pulses, and
• a plurality of aggregate instructions, wherein each of the aggregate instructions link one of the plurality of pulse programs with one of the plurality of steering programs, wherein each of the aggregate instructions comprises an amplitude modulation factor, wherein
• the control circuitry is configured to:
• execute at least one of the plurality of aggregate instructions to link one of the plurality of pulse programs with one of the plurality of steering programs, and
• deliver at least one pulse at one or more electrodes specified by the linked steering program, wherein the delivered one or more pulses has an amplitude specified by the linked pulse program and scaled according to the amplitude modulation factor of the executed aggregate instruction.
