Abstract

Systems and methods make possible the placement of one or more electrode leads in a tissue region for providing functional and/or therapeutic stimulation to tissue. The systems and methods are adapted to provide the relief of pain.

First claim

The invention claimed is:

1. A method to reduce and/or relieve pain in a painful region comprising:
percutaneously inserting a coiled lead into a patient, wherein the coiled lead comprises an electrode and wherein the electrode is in electrical proximity but spaced away from a peripheral nerve;
stimulating the peripheral nerve innervating the painful region via the electrode positioned outside of the painful region, wherein the stimulation comprises a frequency of between 1 and 300 Hz; and
activating the peripheral nerve to alleviate pain in the painful region without functional nerve stimulation at a motor point and without damaging the peripheral nerve.

2. The method of claim 1 , wherein the frequency is between 4 and 20 Hz.

3. The method of claim 1 , wherein the frequency is between 1 and 12 Hz.

4. The method of claim 1 , wherein the frequency is 12 Hz.

5. The method of claim 1 , wherein the frequency is 100 Hz.

6. The method of claim 1 , wherein the stimulation comprises a pulse duration of between 1 and 200 μs.

7. The method of claim 6 , wherein the pulse duration is between 5 and 100 μs.

8. The method of claim 1 , wherein the stimulation comprises an intensity of between 0.1 and 40 mA.

9. The method of claim 8 , wherein the intensity comprises 30 mA.

10. The method of claim 1 further comprising evoking paresthesia over at least a portion of the painful region.

11. The method of claim 10 , wherein the paresthesia is evoked over all of the painful region.

12. The method of claim 1 , wherein the stimulation comprises a pulse duration of between 5 and 100 μs, the stimulation comprises an intensity of 30 mA and the frequency is 12 Hz.

13. The method of claim 12 further comprising evoking paresthesia over at least a portion of the painful region.

14. A system to reduce and/or relieve pain in a painful region, the system comprising:
an electrode positioned in electrical proximity to but spaced away from a peripheral nerve innervating the painful region and wherein the electrode is positioned outside of the painful region; and
an electrical stimulator in operative communication with the electrode, the electrical stimulator applying stimulation through the electrode to the peripheral nerve, wherein the stimulation comprises a frequency of between 1 and 300 Hz and the stimulation is configured to activate the peripheral nerve to alleviate pain in the painful region without functional nerve stimulation at a motor point and without damaging the peripheral nerve.

15. The system of claim 14 , wherein the frequency of the stimulation applied by the electrical stimulator is between 4 and 20 Hz.

16. The system of claim 14 , wherein the frequency of the stimulation applied by the electrical stimulator is between 1 and 12 Hz.

17. The system of claim 14 , wherein the frequency of the stimulation applied by the electrical stimulator is 12 Hz.

18. The system of claim 14 , wherein the frequency of the stimulation applied by the electrical stimulator is 100 Hz.

19. The system of claim 14 , wherein the stimulation applied by the electrical stimulator comprises a pulse duration of between 1 and 200 μs.

20. The system of claim 14 , wherein the pulse duration of the stimulation applied by the electrical stimulator is between 5 and 100 μs.

21. The system of claim 14 , wherein the stimulation applied by the electrical stimulator comprises an intensity of between 0.1 and 40 mA.

22. The system of claim 21 , wherein the intensity comprises 30 mA.

23. A method to reduce and/or relieve pain in a painful region comprising:
percutaneously inserting a coiled lead into a patient, wherein the coiled lead comprises an electrode;
positioning the electrode into adipose or connective tissue outside of the painful region and in electrical proximity to but spaced away from a peripheral nerve;
stimulating the peripheral nerve innervating the painful region via the electrode, wherein the stimulation comprises:
a frequency of between 1 and 300 Hz;
a pulse duration of between 1 and 200 μs; and
an intensity of between 0.1 and 40 mA; and
activating the peripheral nerve to alleviate pain in the painful region without functional nerve stimulation at a motor point and without damaging the peripheral nerve.

24. The method of claim 23 , wherein the frequency is between 4 and 20 Hz.

25. A system to alleviate pain, the system comprising:
a coiled wire lead having a thickness and a diameter configured for percutaneous insertion into a portion of a body that is proximal to a residual limb;
a plurality of electrodes each formed integrally on the lead, wherein the electrodes are spaced apart from one another with an insulated portion positioned between at least two of the plurality of electrodes and wherein the electrodes are configured to be positioned: i) inside the body, and ii) in electrical proximity to but spaced from a portion of at least one nerve; and
an electrical stimulation device operatively coupled to the lead and configured to apply electrical stimulation through the plurality of electrodes to the at least one nerve, to create tingling sensations in a region of residual or phantom pain.

26. A method to reduce and/or relieve pain in a painful region comprising:
percutaneously inserting a coiled lead into a patient, wherein the coiled lead comprises an electrode;
stimulating a peripheral nerve innervating the painful region via an electrode positioned in electrical proximity to but spaced from the peripheral nerve and outside of the painful region, wherein the stimulation comprises a frequency of about 12 Hz;
activating the peripheral nerve to alleviate pain in the painful region without functional nerve stimulation at a motor point and without damaging the peripheral nerve;
stimulating the peripheral nerve innervating the painful region via the electrode, wherein the stimulation comprises a frequency of about 100 Hz; and
activating the peripheral nerve to alleviate pain in the painful region without functional nerve stimulation at the motor point and without damaging the peripheral nerve.
