Abstract

Selective high-frequency spinal chord modulation for inhibiting pain with reduced side affects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient'"'"'s spinal chord region to address low back pain without creating unwanted sensory and/or motor side affects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.

1. A method for treating a patient, comprising:
- delivering or instructing delivery of an electrical signal to the patient'"'"'s spinal cord via at least one implantable signal delivery device to treat the patient; and
  
  wherein the electrical signal has a frequency of from about 1.5 kHz to about 50 kHz and does not create paresthesia in the patient.
- View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 31)
- - 2. The method of claim 31 wherein the pain in the patient includes at least one of low-back pain and leg pain.
  - 3. The method of claim 31 wherein the pain in the patient includes both low-back pain and leg pain.
  - 4. The method of claim 31 wherein the pain in the patient includes pain associated with shingles.
  - 5. The method of claim 4, further comprising placing or instructing placement of the at least one signal delivery device at a thoracic vertebral level.
  - 6. The method of claim 31 wherein the pain in the patient includes pain associated with chronic regional pain syndrome.
  - 7. The method of claim 6, further comprising placing or instructing placement of the at least one signal delivery device at a cervical vertebral level.
  - 8. The method of claim 7 wherein the cervical vertebral level is from about C3 to about C7, inclusive.
  - 9. The method of claim 31 wherein the pain in the patient includes total body pain.
  - 10. The method of claim 9, further comprising placing or instructing placement of the at least one signal delivery device at a cervical vertebral level.
  - 11. The method of claim 10 wherein the cervical vertebral level is from about C3 to about C7, inclusive.
  - 12. The method of claim 31 wherein the pain in the patient includes nociceptive pain.
  - 13. The method of claim 31 wherein the pain in the patient includes pain from surgery.
  - 15. The method of claim 1 wherein the electrical signal has a frequency of from about 5 kHz to about 15 kHz.
  - 16. The method of claim 1 wherein the electrical signal has a frequency of from about 3 kHz to about 15 kHz.
  - 17. The method of claim 1 wherein the electrical signal has a frequency of from about 3 kHz to about 20 kHz.
  - 18. The method of claim 1 wherein the electrical signal has a frequency of from about 3 kHz to about 10 kHz.
  - 19. The method of claim 1 wherein the electrical signal has a frequency of about 10 kHz.
  - 20. The method of claim 1 wherein the at least one signal delivery device is a single electrical lead having a single axial row of electrical contacts.
  - 21. The method of claim 20 wherein the electrical signal is delivered to treat pain in the patient, and wherein the pain in the patient includes bilateral pain.
  - 22. The method of claim 1 wherein the at least one signal delivery device is positioned at a location laterally offset from a midline of the patient'"'"'s spinal cord, and wherein the electrical signal is delivered to treat pain in the patient, and wherein the pain in the patient includes bilateral pain.
  - 23. The method of claim 1, further comprising implanting or instructing implantation of the at least one signal delivery device at a position along the patient'"'"'s spinal cord.
  - 24. The method of claim 1, further comprising placing or instructing placement of the at least one signal delivery device at a position along the patient'"'"'s spinal cord as at least part of a placement process without using or instructing use of patient feedback during the placement process to at least assist in selecting the position.
  - 25. The method of claim 24 wherein placing or instructing placement includes placing or instructing placement of the at least one signal delivery device at a position having an axial location and a lateral location without using or instructing use of patient feedback to adjust one of (a) the axial location of the at least signal delivery device, or (b) the lateral location of the at least one signal delivery device.
  - 26. The method of claim 1, further comprising repeatedly interrupting or instructing interruption of the electrical signal while a therapeutic effect of the electrical signal persists.
  - 27. The method of claim 1 wherein when applied, the electrical signal causes a reduction in the patient'"'"'s reliance on a chemical pain relief remedy having addictive characteristics.
  - 31. The method of claim 1 wherein the electrical signal is delivered to the patient to treat pain in the patient.

14. (canceled)

28. A method for treating a patient, comprising:
- activating or instructing activation of a signal generator to apply an electrical signal to the patient'"'"'s spinal cord via at least one implantable signal delivery device to treat the patient; and
  
  wherein the electrical signal has a frequency of from about 1.5 kHz to about 50 kHz and does not create paresthesia in the patient.

29. A patient treatment device, comprising:
- an implantable signal generator programmed to direct an electrical signal at a frequency of from about 1.5 kHz to about 50 kHz, the implantable signal generator having a first connector coupleable to at least one implantable signal delivery device; and
  
  at least one implantable signal delivery device having a proximal portion and a distal portion, the proximal portion having a second connector coupleable to the first connector of the implantable signal generator, the distal portion having at least one electrical contact for delivering the electrical signal to one or more locations along a patient'"'"'s spinal cord to treat the patient, the patient treatment device being configured to direct the electrical signal to treat the patient without creating paresthesia.

30. A patient treatment device, comprising:
- an implantable signal generator programmed to direct a non-paresthesia-producing electrical signal at a frequency of from about 1.5 kHz to about 50 kHz, the implantable signal generator having a first connector coupleable to at least one implantable signal delivery device; and
  
  at least one implantable signal delivery device having a proximal portion and a distal portion, the proximal portion having a second connector coupleable to the first connector of the implantable signal generator, the distal portion having at least one electrical contact for delivering the electrical signal to one or more locations along a patient'"'"'s spinal cord to treat the patient.
