Abstract: In some embodiments, a method of providing a neurostimulation therapy to a patient, comprises: generating a noise pulse pattern defining a pulse train of pulses to be generated according to a noise profile in an external device; communicated the generated noise pulse pattern to an implantable pulse generator (IPG) of a patient; generating, by the IPG, a series of pulses in sequence for noise stimulation of the patient using the noise pulse pattern from the external device, wherein the IPG applies one or more randomization operations to the pulse pattern from the external device without expanding memory storage for the pulse pattern while maintaining the noise profile of the pulse pattern from the external device; and applying the series of pulses in sequence to neural tissue of the patient using one or more electrodes of one or more stimulation leads.

Abstract: In some embodiments, a method of providing a neurostimulation therapy to a patient, comprises: generating electrical pulses, by an implantable pulse generator (IPG), comprising respective bursts of a plurality of anodic pulses with each anodic pulse being separated by a time gap, wherein (1) the plurality of anodic pulses comprise successively increasing charge; (2) the plurality of anodic pulses are charge limited to be sub-threshold; (3) each burst of anodic pulses is followed by a discharge phase of intermittent time periods to discharge charge build up from the anodic pulses; and (4) each successive intermittent time period increases in time through the discharge phase to avoid action potential (AP) generation; and applying the generated electrical pulses to neural tissue of the patient to inhibit neural activity of the patient.
