Abstract

A system and method for treating auditory dysfunction by somatosensory system stimulation. The system and/or method comprises a probe and a device to stimulate the probe. The probe has a stimulation portion subcutaneously implanted in communication with a predetermined spinal cord site. The stimulation portion of the probe may be implanted externally to the spinal cord, or may be implanted epidurally. The stimulation portion may be a laminotomy, paddle, surgical, or multiple electrode lead. The device to stimulate the probe may also be implanted subcutaneously.

Claims

1. A method of treating auditory dysfunction comprising the steps of:

implanting at least an electrical lead within a patient such that at least one electrode of the electrical lead is disposed adjacent to nerve tissue associated with a vertebral segment;

selecting a plurality of operating parameters for an electrical spinal cord stimulation system that are effective for treating auditory dysfunction;

programming the electrical spinal cord stimulation system according to the plurality of operating parameters; and

activating the electrical stimulation system to deliver electrical pulses to the electrode adjacent to nerve tissue associated with the vertebral segment thereby treating the patient'"'"'s auditory dysfunction.

2. The method of claim 1 wherein nervous tissue is associated with a cervical vertebral segment selected from the group consisting of C1, C2, C3, C4, C5, C6, C7, C8, and a combination thereof.

3. The method of claim 1 wherein the nervous tissue is associated with the dorsal column.

4. The method of claim 1 wherein the electrical stimulation delivers electrical pulses on a substantially continuous basis.

5. The method of claim 1 wherein the plurality of operating parameters include a pulse amplitude parameter, a pulse width parameter, and a pulse frequency parameter.

6. The method of claim 1 wherein the pulse frequency parameter is within the range of about 3 to about 80 Hz.

7. The method of claim 1 wherein the electrical stimulation delivers electrical pulses on a temporary basis in response to receiving an initiation signal from an external control device operated by the patient.

8. The method of claim 1 wherein the selecting comprises:

temporarily delivering electrical pulses according to the plurality of operating parameters to the electrode adjacent to nerve tissue associated with the vertebral segment; and

monitoring the auditory dysfunction while the temporarily delivering is performed.

9. The method of claim 8 wherein the monitoring comprises:

determining an improvement in the auditory dysfunction.

10. The method of claim 8 wherein the auditory dysfunction is tinnitus, hyperacousis, phonophobia, misophonia, auditory agnosia, auditory spatial dysfunction or auditory hallucinations.

11. The method of claim 1 wherein the lead comprises a plurality of electrodes and the plurality of operating parameters include an electrode configuration.

12. The method of claim 1 further comprising adjusting stimulation parameters to optimize auditory dysfunction treatment.

13. The method of claim 1 wherein the auditory dysfunction is tinnitus.

14. A method of treating deafferentation pain comprising the steps of:

implanting at least an electrical lead within a patient such that at least one electrode of the electrical lead is disposed adjacent to nerve tissue associated with a vertebral segment;

selecting a plurality of operating parameters for an electrical spinal cord stimulation system that are effective for treating deafferentation pain;

programming the electrical spinal cord stimulation system according to the plurality of operating parameters; and

activating the electrical stimulation system to deliver electrical pulses to the electrode adjacent to nerve tissue associated with the vertebral segment thereby treating the patient'"'"'s deafferentation pain.

15. The method of claim 14 wherein nervous tissue is associated with a cervical vertebral segment C2 and/or C3.
