Abstract

Methods of treating chronic pain within a patient include applying at least one stimulus to a peripheral nerve within the patient with an implanted system control unit in accordance with one or more stimulation parameters. The stimulus is configured to treat the chronic pain. Systems for treating chronic pain within a patient include a system control unit configured to apply a stimulus to a peripheral nerve within the patient in accordance with one or more stimulation parameters. The system control unit is implanted within the patient and the stimulus is configured to treat the chronic pain.

Claims

1. A method of treating chronic pain within a patient, said method comprising:

subcutaneously implanting a system control unit substantially at or near a location where said patient feels said chronic pain; and

applying at least one stimulus to a peripheral nerve within said patient with an implanted system control unit in accordance with one or more stimulation parameters;

wherein said stimulus is configured to treat said chronic pain.

2. The method of claim 1, wherein said system control unit is coupled to one or more electrodes, and wherein said stimulus comprises a stimulation current delivered via said electrodes.

3. The method of claim 2, wherein said stimulation parameters control at least one or more of a frequency of said stimulation current, a pulse width of said stimulation current, a duty cycle of said stimulation current, a burst pattern of said stimulation current, and an amplitude of said stimulation current.

4. The method of claim 1, further comprising sensing at least one condition related to said chronic pain and using said at least one sensed condition to adjust one or more of said stimulation parameters.

5. The method of claim 1, wherein said system control unit comprises a micro stimulator.

6. The method of claim 1, wherein said system control unit comprises a leadless system control unit.

7. The method of claim 1, wherein said peripheral nerve comprises an occipital nerve.

8. A method of treating chronic pain within a patient, said method comprising:

applying at least one stimulus to a peripheral nerve within said patient with an implanted system control unit in accordance with one or more stimulation parameters;

wherein said stimulus comprises stimulation via one or more drugs delivered to said peripheral nerve and wherein said stimulus is configured to treat said chronic pain.

9. The method of claim 8, wherein said system control unit is coupled to one or more electrodes, and wherein said stimulus further comprises a stimulation current delivered via said electrodes.

10. The method of claim 8, further comprising subcutaneously implanting said system control unit substantially at or near a location where said patient feels said chronic pain.

11. The method of claim 8, wherein said stimulation parameters control at least one or more of an amount of said one or more drugs delivered to said peripheral nerve and a rate of delivery of said one or more drugs to said peripheral nerve.

12. The method of claim 8, further comprising sensing at least one condition related to said chronic pain and using said at least one sensed condition to adjust one or more of said stimulation parameters.

13. The method of claim 8, wherein said system control unit comprises a micro stimulator.

14. The method of claim 8, wherein said system control unit comprises a leadless system control unit.

15. The method of claim 8, wherein said peripheral nerve comprises an occipital nerve.

16. A system for treating chronic pain within a patient, said system comprising:

a system control unit configured to apply a stimulus to a peripheral nerve within said patient in accordance with one or more stimulation parameters;

wherein said system control unit configured to be subcutaneously implanted substantially at or near a location where said patient feels said chronic pain and wherein said stimulus is configured to treat said chronic pain.

17. The system of claim 16, further comprising a pump for delivering one or more drugs, wherein said stimulus comprises stimulation via said one or more drugs delivered by said pump to said peripheral nerve.

18. The system of claim 17, wherein said stimulation parameters control at least one or more of an amount of said one or more drugs delivered to said peripheral nerve and a rate of delivery of said one or more drugs to said peripheral nerve.

19. The system of claim 16, further comprising:

one or more electrodes coupled to said system control unit; and

a pump for delivering one or more drugs;

wherein said stimulus comprises a stimulation current delivered by said system control unit via said electrodes and stimulation via said one or more drugs delivered by said pump.

20. The system of claim 16, further comprising:

a sensor device for sensing at least one condition;

wherein said system control unit uses said at least one sensed condition to adjust one or more of said stimulation parameters.

21. The system of claim 16, wherein said system control unit comprises a micro stimulator.

22. The system of claim 16, wherein said system control unit comprises a leadless system control unit.

23. The system of claim 16, wherein said peripheral nerve comprises an occipital nerve.

24. A system for treating chronic pain within a patient, said system comprising:

means for subcutaneously implanting a system control unit substantially at or near a location where said patient feels said chronic pain; and

means for applying at least one stimulus to a peripheral nerve within said patient with an implanted system control unit in accordance with one or more stimulation parameters;

wherein said stimulus is configured to treat said chronic pain.

25. The system of claim 24, wherein said system control unit is coupled to one or more electrodes, and wherein said stimulus comprises a stimulation current delivered via said electrodes.

26. The system of claim 24, wherein said stimulus comprises stimulation via one or more drugs delivered to said peripheral nerve.

27. A system for treating chronic pain within a patient, said system comprising:

means for applying a drug stimulation to a peripheral nerve within said patient with an implanted system control unit in accordance with one or more stimulation parameters;

wherein said drug stimulation is configured to treat said chronic pain.

28. The system of claim 27, further comprising means for applying an electrical stimulation to said peripheral nerve within said patient with said implanted system control unit in accordance with said one or more stimulation parameters.
