Abstract
The present disclosure provides systems and methods for generating burst waveforms. An implantable neurostimulation system includes an implantable stimulation lead including a plurality of contacts, and an implantable pulse generator communicatively coupled to the stimulation lead. The pulse generator is configured to generate a waveform including a burst that includes a leading anodic pulse followed by alternating cathodic pulses and anodic pulses, each cathodic pulse in the burst having a greater amplitude than the previous cathodic pulse.

An implantable neurostimulation system for generating burst waveforms, the neurostimulation system comprising:
- an implantable stimulation lead comprising a plurality of contacts;
- and
- an implantable pulse generator communicatively coupled to the stimulation lead and configured to:
- generate a waveform including a burst that includes a leading anodic pulse followed by alternating cathodic pulses and anodic pulses, each cathodic pulse in the burst having a greater amplitude than the previous cathodic pulse, wherein the burst further includes a passive discharge following a last cathodic pulse, the passive discharge decaying from a positive value to zero.
An implantable pulse generator for generating burst waveforms, the pulse generator comprising:
- a memory device;
- and
- a processor coupled to the memory device, the processor configured to generate a waveform including a burst that includes a leading anodic pulse followed by alternating cathodic pulses and anodic pulses, each cathodic pulse in the burst having a greater amplitude than the previous cathodic pulse, wherein the burst further includes a passive discharge following a last cathodic pulse, the passive discharge decaying from a positive value to zero.
A method of applying neurostimulation, the method comprising:
- generating, using an implantable pulse generator, a waveform including a burst that includes a leading anodic pulse followed by alternating cathodic pulses and anodic pulses, each cathodic pulse in the burst having a greater amplitude than the previous cathodic pulse, wherein the burst further includes a passive discharge following a last cathodic pulse, the passive discharge decaying from a positive value to zero;
- and
- applying the waveform to a patient using an implantable stimulation lead coupled to the implantable pulse generator.
