Abstract

The present application relates to a new stimulation design which can be utilized to treat neurological conditions. The stimulation system produces a combination of burst and tonic stimulation which alters the neuronal activity of the predetermined site, thereby treating the neurological condition or disorder.

First claim

What is claimed is:

1. A method of treating chronic pain in a patient with reduced paresthesia, the method comprising:
programming an implantable pulse generator to operate according to burst stimulation parameters that define stimulation pulses to be repeated in bursts, wherein the burst stimulation parameters include a pulse repetition frequency of at least 200 Hz, a burst rate of at least 18 Hz, and a pulse width of approximately 1 ms;
generating, by the implantable pulse generator, a tonic stimulation pulse to be repeated as tonic stimulation;
generating, by the implantable pulse generator, burst stimulation according to the stimulation parameters, wherein the burst stimulation includes a plurality of bursts with each burst including a plurality of pulses having the pulse width repeating at the pulse repetition frequency followed by quiescent periods such that bursts within the plurality of bursts repeat at the burst rate;
providing the burst stimulation from the implantable pulse generator to a stimulation lead; and
applying the burst stimulation to nerve tissue of the patient via one or more electrodes of the stimulation lead, wherein the burst and tonic stimulation cause the patient to experience pain relief with reduced paresthesia.

2. The method of claim 1 wherein the applying applies the burst stimulation to the spinal cord of the patient.

3. The method of claim 1 wherein the applying applies the burst stimulation to a dorsal root ganglion of the patient.

4. The method of claim 1 wherein each burst of the plurality of bursts includes at least five (5) pulses.

5. The method of claim 1 further comprising:
programming the implantable pulse generator with one or more tonic stimulation parameters that define at least one stimulation pulse, of the tonic stimulation, to be repeated in a tonic manner; and
generating, by the implantable pulse generator, a combination of the burst stimulation and tonic stimulation according to the tonic and burst stimulation parameters.

6. The method of claim 5 , wherein the tonic and burst parameters are stimulation program parameters that are repeated in stimulation cycles by the implantable pulse generator.

7. The method of claim 5 , wherein the burst and tonic stimulation are applied to nerve tissue of the patient using different electrode combinations.

8. The method of claim 5 , wherein the generating generates a respective pulse for the tonic stimulation immediately before beginning pulses for an individual burst of the burst stimulation.

9. The method of claim 5 further wherein pulses for the tonic stimulation are generated between an occurrence of a first pulse of a respective burst and a last burst of the respective burst of the burst stimulation.

10. The method of claim 5 wherein the burst stimulation is configured to treat, in addition to pain relief, at least one of a movement disorder, a sensory disorder, or tinnitus.

11. An implantable pulse generator (IPG) for treating chronic pain in a patient with reduced paresthesia, comprising:
memory configured to store program instructions, the memory further configured to store burst stimulation parameters that define stimulation pulses to be repeated in bursts, wherein the burst stimulation parameters include a pulse repetition frequency of at least 200 Hz, a burst rate of at least 18 Hz, and a pulse width of approximately 1 ms;
a pulse generator;
a processor that, when executing the program instructions, directs the pulse generator to:
generate a tonic stimulation pulse to be repeated as tonic stimulation; and
generate burst stimulation according to the stimulation parameters, wherein the burst stimulation includes a plurality of bursts with each burst including a plurality of pulses having the pulse width repeating at the pulse repetition frequency followed by quiescent periods such that bursts within the plurality of bursts repeat at the burst rate; and
a stimulation lead configured to apply the burst stimulation to nerve tissue of the patient via one or more electrodes of the stimulation lead, wherein the burst and tonic stimulation are configured to cause the patient to experience pain relief with reduced paresthesia.

12. The IPG of claim 11 wherein the stimulation lead is configured to apply the burst stimulation to the spinal cord of the patient.

13. The IPG of claim 11 wherein the stimulation lead is configured to apply the burst stimulation to a dorsal root ganglion of the patient.

14. The IPG of claim 11 wherein each burst of the plurality of bursts includes at least five (5) pulses.

15. The IPG of claim 11 wherein the memory is configured to store one or more tonic stimulation parameters that define at least one stimulation pulse to be repeated in a tonic manner; and the processor is configured to direct the pulse generator to generate a combination of the burst stimulation and tonic stimulation according to the tonic and burst stimulation parameters.

16. The IPG of claim 15 wherein the tonic and burst parameters are stimulation program parameters that are repeated in stimulation cycles by the implantable pulse generator.

17. The IPG of claim 15 wherein the stimulation lead is configured to apply the burst and tonic stimulation to nerve tissue of the patient using different electrode combinations.

18. The IPG of claim 15 , wherein the pulse generator is configured to generate a respective pulse for the tonic stimulation immediately before beginning pulses for an individual burst of the burst stimulation.

19. The IPG of claim 15 wherein the pulse generator is configured to generate the pulses for the tonic stimulation between an occurrence of a first pulse of a respective burst and a last burst of the respective burst of the burst stimulation.

20. The IPG of claim 15 wherein the burst stimulation is configured to treat, in addition to pain relief, at least one of a movement disorder, a sensory disorder, or tinnitus.
