Abstract

Selective high-frequency spinal cord modulation for inhibiting pain with reduced side effects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 100 KHz may be applied to the patient'"'"'s spinal cord region to address headache pain without creating paresthesia in the patient.

Claims

1. A method of treating a headache pain indication, exclusive of headache pain associated with total body pain, comprising:

configuring a signal generator to generate and deliver a headache pain therapy signal to a target location, wherein the target location is a cervical vertebral location between C1-C5, inclusive, via one or more implanted signal delivery devices coupled to the signal generator,

wherein at least a portion of the therapy signal is at a frequency in a frequency range of 1.5 kHz to 100 kHz, includes pulses with a pulse width in a pulse width range of 10 microseconds to 333 microseconds, and has an amplitude in an amplitude range of 0.1 mA to 20 mA, which at least partially alleviates the headache pain indication, exclusive of headache pain associated with total body pain, without generating paresthesia.

2. The method of claim 1, wherein the cervical vertebral location is between C1-C3, inclusive.

3. The method of claim 1, wherein the cervical vertebral location is between C2-C4, inclusive.

4. The method of claim 1, wherein the headache pain indication is selected from the group consisting of:

herpes zoster headache pain, cluster headache pain, swimmer'"'"'s headache pain, analgesic rebound headache pain, and occipital neuralgia headache pain.

5. The method of claim 1, wherein the headache pain indication is migraine pain.

6. The method of claim 1, wherein the frequency range is 3 kHz to 20 kHz.

7. The method of claim 1, wherein the frequency range is 5 kHz to 15 kHz.

8. The method of claim 1, wherein the one or more signal delivery devices include a percutaneous lead having one or more electrodes disposed toward a distal end of the percutaneous lead.

9. A method of treating a non-total body pain headache pain indication, comprising:

applying an electrical therapy signal to a cervical vertebral location of a patient'"'"'s spinal cord, wherein the cervical vertebral location is between C1-C5, inclusive, wherein at least a portion of the electrical therapy signal (a) is at a frequency in a frequency range of 1.5 kHz to 100 kHz, (b) has electrical pulses with a pulse width in a pulse width range of 10 microseconds to 333 microseconds, and (c) is at an amplitude in an amplitude range of 0.1 mA to 20 mA, and wherein the electrical therapy signal treats the headache pain indication without generating paresthesia in the patient.

10. The method of claim 9, wherein the cervical vertebral location is between C2-C4, inclusive.

11. The method of claim 9, wherein the headache pain indication is selected from the group consisting of:

herpes zoster headache pain, cluster headache pain, swimmer'"'"'s headache pain, analgesic rebound headache pain, and occipital neuralgia headache pain.

12. The method of claim 9, wherein the headache pain indication is migraine pain.

13. The method of claim 9, wherein the frequency range is 3 kHz to 20 kHz.

14. The method of claim 9, wherein the frequency range is 5 kHz to 15 kHz.

15. The method of claim 9, further comprising programming the signal generator to generate the electrical therapy signal.

16. The method of claim 9,

wherein the electrical therapy signal is applied via one or more implanted signal delivery devices coupled to an implanted signal generator, wherein the signal generator is programmed with instructions that, when executed, treat the headache pain indication by generating the electrical therapy signal and delivering the electrical therapy signal to the cervical vertebral location.

17. The method of claim 16, wherein the one or more signal delivery devices include a percutaneous lead having one or more electrodes disposed toward a distal end of the percutaneous lead.

18. The method of claim 9 wherein the frequency range is 1.5 kHz to 50 kHz.

19. The method of claim 9 wherein the frequency range is 3 kHz to 10 kHz.

20. The method of claim 9 wherein the frequency is 10 kHz.

21. The method of claim 9 wherein the portion of the electrical therapy signal is biphasic.

22. The method of claim 9 wherein the pulse width range is 25 microseconds to 166 microseconds.

23. The method of claim 9 wherein the pulse width range is 30 microseconds to 35 microseconds.

24. The method of claim 9 wherein the frequency range is 5 kHz to 15 kHz, the pulse width range is 30 microseconds to 35 microseconds, and the amplitude range is 0.5 mA to 10 mA.

25. A headache pain treatment system for treating a non-total body pain headache pain indication, comprising:

a spinal cord modulation system having

at least one signal delivery device configured to be implanted proximate to a cervical vertebral location of a patient'"'"'s spinal cord, wherein the cervical vertebral location is between C1-C5, inclusive, and

a signal generator programmed with instructions that, when executed, treat the headache pain indication by generating and delivering a non-paresthesia-generating electrical therapy signal to the cervical vertebral location, via the at least one signal delivery device,

wherein at least a portion of the electrical therapy signal (a) is at a frequency in a frequency range of 1.5 kHz to 100 kHz, (b) includes pulses having a pulse width in a pulse width range of 10 microseconds to 333 microseconds, and (c) is at an amplitude in an amplitude range of 0.1 mA to 20 mA.

26. The system of claim 25, wherein the cervical vertebral location is between C2-C4, inclusive.

27. The system of claim 25, wherein the headache pain indication is selected from the group consisting of:

herpes zoster headache pain, cluster headache pain, swimmer'"'"'s headache pain, analgesic rebound headache pain, and occipital neuralgia headache pain.

28. The system of claim 25, wherein the headache pain indication is migraine pain.

29. The system of claim 25, wherein the frequency range is 3 kHz to 20 kHz.

30. The system of claim 25, wherein the frequency range is 5 kHz to 15 kHz.
