Abstract

A method is provided, including physically contacting a gastric implantation site of a stomach via a transluminal approach, physically contacting the site via a transabdominal approach, stabilizing the site, and implanting an electrode at the site based on the physical contact provided by the transluminal and transabdominal approach. Other embodiments are also described.

Claims

1. An implantation system, comprising:

an electrode, configured for implantation at a gastric implantation site of a patient; and

an endoscope configured to provide access to the gastric implantation site, to stabilize itself and the site with respect to each other by using suction, and to facilitate insertion of the electrode into the gastric implantation site.

2. The system according to claim 1, wherein the electrode is disposed within the endoscope prior to being inserted into the gastric implantation site.

3. The system according to claim 1, wherein a distal tip of the endoscope is configured to be within the stomach, adjacent to the implantation site, when the electrode is inserted into the implantation site.

4. A method, comprising:

passing into a stomach of a patient an endoscope having electrode apparatus, the electrode apparatus including at least one electrode;

pushing the electrode apparatus through a wall of the stomach to a site outside of the stomach;

moving the electrode apparatus while it is outside of the stomach in a manner that places the electrode in contact with the stomach wall; and

leaving the electrode in the stomach wall.

5. The method according to claim 4, wherein the stomach wall includes a muscular layer, and wherein leaving the electrode comprises leaving the electrode in the muscular layer.

6. The method according to claim 4, wherein the stomach wall includes a submucosal layer, and wherein leaving the electrode comprises leaving the electrode in the submucosal layer.

7. A method, comprising:

passing electrode apparatus into a stomach of a patient, the electrode apparatus including at least one electrode;

pushing the electrode apparatus through a wall of the stomach to a site outside of the stomach;

moving the electrode apparatus while it is outside of the stomach in a manner that places the electrode in contact with the stomach wall; and

leaving the electrode in the stomach wall.

8. The method according to claim 7, wherein the stomach wall includes a muscular layer, and wherein leaving the electrode comprises leaving the electrode in the muscular layer.

9. The method according to claim 7, wherein the stomach wall includes a submucosal layer, and wherein leaving the electrode comprises leaving the electrode in the submucosal layer.

10. The method according to claim 7, wherein passing the electrode apparatus comprises passing an endoscope to which the electrode apparatus is coupled.

11. The method according to claim 7, wherein the electrode apparatus includes at least one needle electrode, and wherein leaving the electrode comprises leaving the needle electrode in the stomach wall.

12. A method for implanting gastric leads, comprising:

applying positive gas pressure through one lumen of an endoscope;

applying negative gas pressure through another lumen of the endoscope; and

implanting the leads using the endoscope.

13. An implantation system, comprising:

transluminal apparatus configured to provide access to a gastric implantation site of a patient and to apply pressure to the gastric implantation site;

an electrode, configured for implantation at the implantation site; and

abdominal cavity apparatus configured to be positioned within an abdomen of the patient, outside of the stomach,

wherein the system is configured such that application of the pressure by the transluminal apparatus facilitates insertion of the electrode into the wall by the abdominal cavity apparatus.

14. The system according to claim 13, wherein the transluminal apparatus is configured to apply the pressure in a manner that brings the site adjacent to an abdominal wall of the patient.

15. The system according to claim 13, wherein the transluminal apparatus comprises at least one endoscope.

16. The system according to claim 13, wherein, prior to the insertion of the electrode, the transluminal apparatus and the abdominal cavity apparatus are independently manipulatable.

17. The system according to claim 13, wherein the transluminal apparatus is configured to apply suction to the gastric implantation site.

18. The system according to claim 13, wherein the electrode comprises a needle electrode.

19. The system according to claim 13, wherein the abdominal cavity apparatus is configured to be passed through an abdominal wall of the patient, towards the stomach.

20. The system according to claim 13, wherein a distal tip of the transluminal apparatus is configured to be within the stomach, adjacent to the implantation site, when the abdominal cavity apparatus inserts the electrode into the wall.

21. The system according to claim 13, wherein the transluminal apparatus is configured to apply the pressure by inflating the stomach.

22. The system according to claim 13, wherein a physical portion of the transluminal apparatus is configured to apply the pressure to the gastric implantation site.

23. The system according to claim 22, wherein the physical portion of the transluminal apparatus comprises a tip of the transluminal apparatus.

24. The system according to claim 13, wherein the abdominal cavity apparatus is configured to be coupled to the transluminal apparatus at least during the insertion of the electrode.

25. The system according to claim 24, wherein the abdominal cavity apparatus is in contact with the transluminal apparatus at least during the insertion of the electrode.

26. A method, comprising:

physically contacting a gastric implantation site of a stomach via a transluminal approach;

physically contacting the site via a transabdominal approach;

stabilizing the site; and

implanting an electrode at the site based on the physical contact provided by the transluminal and transabdominal approach.

27. The method according to claim 26, wherein stabilizing the site comprises inflating the stomach.

28. The method according to claim 26, wherein stabilizing the site comprises applying pressure to the stomach.

29. The method according to claim 26, wherein stabilizing the site comprises applying suction.
