Abstract

Some implementations provide a method of treating chronic pain or inflammation with neural modulation, the method including: placing a surgical instrument to reach into a torso section of a patient'"'"'s body, the patient suffering from chronic pain or inflammation in a primary area in the torso section; placing a wireless device into an opening on the surgical instrument, the wireless device suitable to fit into the opening and configured to receive electromagnetic energy non-inductively from a source located outside the patient'"'"'s body; through the opening on the surgical instrument, positioning the wireless electrode lead adjacent to or near excitable tissue in the primary area in the torso section of the patient; and causing electrical pulses to be delivered to one or more electrodes on the wireless device such that neural modulation is applied to the excitable tissue in the primary area in the torso section.

Claims

1. A method of treating chronic pain or inflammation with neural modulation, the method comprising:

placing a surgical instrument to reach into a torso section of a patient'"'"'s body, the patient suffering from chronic pain or inflammation in a primary area in the torso section;

placing a passive wireless stimulator device into an opening on the surgical instrument by placing a passive wireless stimulator device that includes one or more non-inductive antennas configured to receive electromagnetic energy radiated from a source located outside of the patient'"'"'s body, electronic circuitry coupled to each of the one or more non-inductive antennas and configured to extract electric power and excitation pulses from the radiated electromagnetic energy as received by the one or more non-inductive antennas, and one or more electrodes configured to deliver the excitation pulses to the one or more excitable tissue to effectuate the neural modulation thereof, the passive wireless stimulator device suitable to fit into the opening on the surgical instrument and configured to operate without a battery or energy storage by receiving electromagnetic energy non-inductively from a source located outside the patient'"'"'s body;

through the opening on the surgical instrument, positioning one or more electrodes on the passive wireless stimulator device adjacent to or near excitable tissue in the primary area in the torso section of the patient; and

causing electrical pulses to be delivered to one or more electrodes on the passive wireless stimulator device such that neural modulation is applied to the excitable tissue in the primary area in the torso section.

2. The method of claim 1, wherein placing the surgical instrument comprises positioning a laparoscopic device into an abdominal region of the patient'"'"'s body.

3. The method of claim 2, wherein placing a passive wireless stimulator device into an opening on the surgical instrument comprises placing the passive wireless stimulator device through a working channel or cannula of the laparoscopic device.

4. The method of claim 3, wherein positioning the passive wireless stimulator device adjacent to or near excitable tissue comprises positioning the passive wireless stimulator device adjacent to or near branches of the splenic nerve of the patient.

5. The method of claim 3, wherein positioning the passive wireless stimulator device adjacent to or near excitable tissue comprises positioning the wireless device adjacent to or near nerves within the spinal cord of the patient.

6. The method of claim 3, wherein positioning the passive wireless stimulator device adjacent to or near excitable tissue comprises positioning the passive wireless stimulator device adjacent to or near branches of the splanchnic nerve of the patient.

7. The method of claim 3, wherein positioning the passive wireless stimulator device adjacent to or near excitable tissue comprises positioning the wireless device adjacent to or near branches of the vagus nerve of the patient.

8. The method of claim 3, wherein positioning the passive wireless stimulator device adjacent to or near excitable tissue comprises positioning the wireless device adjacent to or near the celiac ganglion of the patient.

9. The method of claim 3, wherein positioning the passive wireless stimulator device adjacent to or near excitable tissue comprises positioning the passive wireless stimulator device adjacent to or near the phrenic nerve and the renal plexus of the patient.

10. The method of claim 1, wherein placing the surgical instrument comprises placing an endoscopic device into the torso section of the patient'"'"'s body.

11. The method of claim 10, wherein placing a passive wireless stimulator device into an opening on the surgical instrument comprises placing the passive wireless stimulator device through a working channel or cannula of the endoscopic device.

12. The method of claim 11, wherein positioning the passive wireless stimulator device adjacent to or near excitable tissue comprises positioning the wireless device in a region in the gastro-intestinal tract or the respiratory tract of the patient.

13. The method of claim 1, wherein placing the surgical instrument comprises placing a catheter device into a thoracic region of the patient'"'"'s body.

14. The method of claim 13, wherein placing a passive wireless stimulator device into an opening on the surgical instrument comprises placing the wireless device through a working channel or cannula of the catheter device.

15. The method of claim 1, wherein positioning the passive wireless stimulator device adjacent to or near excitable tissue comprises positioning the passive wireless stimulator device adjacent to or near nerves on at least one of:

stomach, heart, spleen, pancreas, diaphragm, liver, or kidney of the patient.

16. The method of claim 15, wherein positioning the passive wireless stimulator device adjacent to or near excitable tissue further comprises positioning the device adjacent to or near the pancreas of the patient, and wherein causing neural modulation to be applied to the excitable tissue comprises causing sufficient neural modulation such that inflammation is reduced in the pancreas of the patient.

17. The method of claim 15 wherein causing sufficient neural modulation further comprises causing sufficient neural modulation to the TRPV1 and/or CGRP-containing neurons such that inflammation is reduced in the pancreas of the patient.

18. The method of claim 1, wherein causing neural modulation to be applied to the excitable tissue further comprises causing neural modulation of the sympathetic nervous system of the patient.

19. The method of claim 18, wherein causing neural modulation of the sympathetic nervous system of the patient comprises causing neural activation of the greater splanchnic nerve of the patient.

20. The method of claim 19, wherein causing neural modulation of the sympathetic nervous system of the patient comprises causing neural inhibition of the greater splanchnic nerve of the patient.

21. The method of claim 1, further comprising using X-Ray fluoroscopy to guide positioning the passive wireless stimulator device adjacent to or near one or more excitable tissue.

22. The method of claim 1, further comprising using ultrasound sonography to guide positioning the wireless electrode lead on the passive wireless stimulator device adjacent to or near one or more excitable tissue.
