Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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 a charge output by the leading anodic pulse is less than a charge output by a first cathodic pulse; and applying the waveform to a patient using an implantable stimulation lead coupled to the implantable pulse generator. 2. The method of claim 1 , wherein the burst further includes a passive discharge following a last cathodic pulse, the passive discharge decaying from a positive value to zero. 3. The method of claim 1 , wherein the cathodic pulses are square wave cathodic pulses. 4. The method of claim 1 , wherein the leading anodic pulse and the subsequent anodic pulses have a same pulse width and amplitude. 5. The method of claim 1 , wherein a pulse width of the leading anodic pulse is greater than a pulse width of the cathodic pulses, and wherein the pulse width of the leading anodic pulse is between 400 μs and 1000 μs. 6. The method of claim 1 , wherein the burst further includes an inter-phase gap between each anodic and cathodic pulse. 7. The method of claim 6 , wherein the inter-phase gap has a length of 100 μs or less. 8. The method of claim 1 , wherein the pulse width of each cathodic pulse is between 60 μs and 400 μs. 9. The method of claim 1 , wherein a total number of anodic pulses within the burst is in a range from two to eight pulses. 10. The method of claim 1 , wherein each cathodic pulse is 20% larger than the previous cathodic pulse. 11. The method of claim 1 , wherein the leading anodic pulse has a pulse width of 1000 μs. 12. The method of claim 1 , wherein each cathodic pulse has a pulse width of 300 μs.
