Abstract

The disclosure describes an implantable neurostimulator device for delivery of neurostimulation to treat head, neck, or facial pain or tension, including pain or tension caused by occipital neuralgia. The device may be a neurostimulation device having a miniaturized housing with a low profile that permits subcutaneous implantation at a stimulation site directly adjacent a neuralgic region at the back of the neck of a patient. For example, the device may be subcutaneously implanted at the back of the neck of a patient to relieve symptoms of occipital neuralgia.

Claims

1. A method comprising controlling, via one or more processors, delivery of electrical stimulation to a patient from an electrical stimulation device implanted in a subcutaneous region within a back of a neck of the patient, wherein the electrical stimulation device includes an at least partially bendable housing, and wherein the housing is bent to at least partially conform the housing to the subcutaneous region within the back of the neck of the patient.

2. The method of claim 1, further comprising implanting the electrical stimulation device in the subcutaneous region within the back of the neck of the patient.

3. The method of claim 1, wherein the electrical stimulation is configured to treat symptoms of occipital neuralgia.

4. The method of claim 1, wherein the electrical stimulation is configured to treat at least one of pain or tension in at least one of a head, neck or facial region of a patient.

5. The method of claim 1, further comprising bending the housing to at partially conform the housing to the subcutaneous region within the back of the neck of the patient.

6. The method of claim 1, wherein the electrical stimulation device includes at least one electrode and a flexible member that at least partially encapsulates the at least partially bendable housing, and wherein the at least one electrode protrudes through the flexible member.

7. The method of claim 1, wherein the electrical stimulation device includes at least one electrode, wherein the at least partially bendable housing defines a degree of curvature such that a side of the housing is concave, wherein the at least one electrode is formed on the side of the housing, and wherein the electrical stimulation device is placed within the subcutaneous region such that the at least one electrode faces inward toward subcutaneous tissue.

8. The method of claim 1, wherein the at least partially bendable housing defines a hole, and wherein a suture is placed through the hole to anchor the electrical stimulation device at a stimulation site in the subcutaneous region.

9. The method of claim 1, wherein the electrical stimulation device include a plurality of electrodes arranged in a two-dimensional array on a surface of the housing.

10. A method comprising controlling, via one or more processors, delivery of electrical stimulation to a patient from an electrical stimulation device implanted in a subcutaneous region within a back of a neck of the patient, wherein the electrical stimulation device includes a housing and at least one electrode formed on a side of the housing, wherein the housing defines a degree of curvature such that the side is concave, and wherein the electrical stimulation device is placed within the subcutaneous region such that the at least one electrode faces inward toward subcutaneous tissue.

11. The method of claim 10, further comprising implanting the electrical stimulation device in the subcutaneous region within the back of the neck of the patient.

12. The method of claim 10, wherein the electrical stimulation is configured to treat symptoms of occipital neuralgia.

13. The method of claim 10, wherein the electrical stimulation is configured to treat at least one of pain or tension in at least one of a head, neck or facial region of a patient.

14. The method of claim 10, further comprising placing the electrical stimulation device within the subcutaneous region such that the at least one electrode faces inward toward subcutaneous tissue.

15. The method of claim 10, wherein the electrical stimulation device includes a flexible member that at least partially encapsulates the housing, and wherein the at least one electrode protrudes through the flexible member.

16. The method of claim 10, wherein the housing that defines a hole, and wherein a suture is placed through the hole to anchor the electrical stimulation device at a stimulation site in the subcutaneous region.

17. The method of claim 10, wherein the housing is at least partially bendable, and wherein the housing is bent to at least partially conform the housing to the subcutaneous region within the back of the neck of the patient.

18. The method of claim 10, wherein the electrical stimulation device include a plurality of electrodes arranged in a two-dimensional array on a surface of the housing.

19. A method comprising controlling, via one or more processors, delivery of electrical stimulation to a patient from an electrical stimulation device implanted in a subcutaneous region within a back of a neck of the patient, wherein the electrical stimulation device includes a housing, at least one electrode, and a flexible member that at least partially encapsulates the housing, wherein the device housing is shaped to at least partially conform to the subcutaneous region within the back of the neck of the patient, and wherein the at least one electrode protrudes through the flexible member.

20. The method of claim 19, further comprising implanting the electrical stimulation device in the subcutaneous region within the back of the neck of the patient.

21. The method of claim 19, wherein the electrical stimulation is configured to treat symptoms of occipital neuralgia.

22. The method of claim 19, wherein the electrical stimulation is configured to treat at least one of pain or tension in at least one of a head, neck or facial region of a patient.

23. The method of claim 19, further comprising the electrical stimulation device within the subcutaneous region such that the ate least one electrode faces inward toward subcutaneous tissue.

24. The method of claim 19, wherein the electrical stimulation device includes an electrical stimulation generator that generates the electrical stimulation, a battery within the housing that powers the stimulation generator, wherein the at least one electrode is coupled to the stimulation generator to deliver the electrical stimulation, and wherein the housing houses the stimulation generator and the battery.

25. The method of claim 19, wherein the housing defines a hole, and wherein a suture is placed through the hole to anchor the electrical stimulation device at a stimulation site in the subcutaneous region.

26. The method of claim 19, wherein the housing is at least partially bendable, and wherein the housing is bent to at least partially conform the housing to the subcutaneous region within the back of the neck of the patient.

27. The method of claim 19, wherein the electrical stimulation device includes a plurality of electrodes arranged in a two-dimensional array on a surface of the housing.
