Abstract

The present invention involves a method and a system for using electrical stimulation to treat gastrointestinal and/or eating disorders. More particularly, the method comprises surgically implanting an electrical stimulation lead that is in communication with predetermined thoracic vertebral segments to cause spinal nervous tissue stimulation, thus treating a wide variety of gastrointestinal disorders.

Claims

1-9. -9. (canceled)

10. A method of treating gastroparesis, comprising:

implanting at least one electrical lead of an electrical spinal cord stimulation system within the epidural space of a patient such that at least one electrode of the electrical lead is disposed adjacent to nerve tissue of the patient'"'"'s spinal cord within a thoracic vertebral segment;

selecting a plurality of operating parameters for the electrical spinal cord stimulation system that are effective for treating the gastrointestinal disorder;

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

treating the patient'"'"'s gastroparesis by increasing gastric motility by activating the electrical spinal cord stimulation system to deliver electrical pulses to the electrode adjacent to the nerve tissue within the thoracic vertebral segment.

12. The method of claim 10 wherein the electrical spinal cord stimulation system delivers electrical pulses on a temporary basis in response to receiving an initiation signal from an external control device operated by the patient.

14. The method of claim 10 wherein the plurality of operating parameters include a pulse amplitude parameter, a pulse width parameter, and a pulse frequency parameter.

15. The method of claim 10 wherein the pulse frequency parameter is within the range of 10-350 Hz.

16. The method of claim 10 wherein the lead comprises a plurality of electrodes and the plurality of operating parameters include an electrode configuration.

17. The method of claim 10 wherein the selecting comprises:

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

monitoring gastric activity that occurs while the temporarily delivering is performed.

18. The method of claim 17 wherein the monitoring comprises:

determining gastric motility by measuring pressure generated by contraction of muscles of the stomach and/or small intestine.

19. The method of claim 10 wherein the at least one electrode is implanted within the T5/T6 epidural space of the patient.

20. The method of claim 10, wherein the electrical spinal cord stimulation delivers electrical pulses on a substantially continuous basis.

21. The method of claim 10, wherein the gastroparesis is associated with diabetes.
