1. Apparatus comprising:
- an electrode;
a lead, coupled to the electrode; and
an implantation tool, which comprises;
a securing device, which is configured to secure the implantation tool to a portion of a gastric wall of a patient; and
an element which is configured to puncture and move distally through the portion of the gastric wall, and subsequently draw the electrode proximally through the portion of the gastric wall to insert the electrode into the gastric wall generally in parallel to the gastric wall,wherein the implantation tool is configured to be removed from a body of the patient after implanting the electrode, such that only the electrode and the lead remain in the body.

5. Apparatus, comprising:
-
an electrode; a lead, coupled to the electrode; and
,an implantation tool, which comprises a longitudinal element shaped to define a sharp distal tip that is configured to puncture a gastric wall of a patient, wherein a distal portion of the electrode is parallel to a distal portion of the longitudinal element, wherein the electrode is coupled to the implantation tool such that distal advancement of the implantation tool in the gastric wall advances the electrode in the gastric wall generally in parallel to the gastric wall, wherein the implantation tool is configured to permit decoupling of the electrode from the longitudinal element defining the sharp tip following implantation of the electrode in the gastric wall, and wherein the implantation tool is configured to be removed from a body of the patient after implanting the electrode, such that only the electrode and the lead remain in the body. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)

14. Apparatus, comprising:
-
two electrodes; and an implantation tool, which (a) is configured to implant the electrodes in a gastric wall of a patient, without removing the implantation tool from a body of the patient between successive electrode implantations, and (b) comprises a cartridge, within which are removably disposed the two electrodes, wherein the cartridge is generally cylindrical in shape, and is configured (a) to implant a first one of the electrodes, (b) subsequently to be rotated, and (c) subsequently to implant a second one of the electrodes. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A method comprising:
-
providing an electrode and a lead coupled to the electrode; using a securing device of an implantation tool, securing the implantation tool to a portion of a gastric wall of a patient; puncturing and moving distally an element of the implantation tool through the portion of the gastric wall, and subsequently using the element to draw the electrode proximally through the portion of the gastric wall, thereby inserting the electrode into the gastric wall generally in parallel to the gastric wall; and removing the implantation tool from a body of the patient after implanting the electrode, such that only the electrode and the lead remain in the body.

24. A method comprising:
-
providing an electrode and a lead coupled to the electrode; providing an implantation tool, which includes a longitudinal element shaped to define a, sharp distal tip that is configured to puncture a gastric wall of a patient, wherein a distal portion of the electrode is parallel to a distal portion of the longitudinal element; distally advancing the implantation tool in the gastric wall so as to advance the electrode in the gastric wall generally in parallel to the gastric wall; decoupling the electrode from the longitudinal element defining the sharp tip following implantation of the electrode in the gastric wall; and removing the implantation tool from a body of the patient after implanting the electrode, such that only the electrode and the lead remain in the body. - View Dependent Claims (25)
