Arbitrary waveform generator and neural stimulation application with scalable waveform feature

摘要

A method, device and/or system for generating arbitrary scalable waveforms of a desired shape that can be used for generating a stimulation pulse for medical purposes such as for spinal cord stimulation therapy, where scaling function(s) can be used to scale arbitrary waveforms for increased flexibility and which can also be used for charge balancing purposes as well.

1. A method for providing a therapy to a patient, said method comprising the steps of:
providing a waveform generating circuit for generating a waveform of a desired shape having an amplitude and a duration; defining a scaling factor; using said scaling factor for scaling the waveform generated by said waveform generating circuit, such that both the amplitude and the duration of the waveform is adjusted using said scaling factor; and providing a stimulation pulse including at least a substantial portion that is based on said scaled waveform having shape resembling the desired shape of the waveform for stimulating a stimulation region of the patient.
