9. Apparatus comprising:
-
one or more electrodes, adapted to be placed in contact with a wall of a lumen of a duodenum of a subject;
a control unit, adapted to drive the electrodes to apply a current to the wall of the duodenal lumen, and to configure the current to stimulate a site selected from the group consisting of;
a vagus nerve of the subject, and enteric nervous system (ENS) tissue of the subject. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. Apparatus comprising:
-
an eating sensor, adapted to be placed in a body of a subject, and to generate a signal indicative of eating by the subject;
a stimulator adapted to stimulate a site selected from the group consisting of;
a vagus nerve of the subject and enteric nervous system (ENS) tissue of the subject, and adapted to be placed in a gastrointestinal tract of the subject;
one or more electrodes, adapted to be implanted at respective duodenal sites of the subject; and
a control unit, adapted to receive the eating signal, and, responsively thereto, to drive the stimulator to apply a first current to the selected site of the subject, and to drive the one or more electrodes to apply a second current that modulates activity of pancreatic beta cells of the subject. - View Dependent Claims (18, 19, 20)

24. A method comprising:
-
inserting one or more helical electrodes into a duodenum of a subject;
expanding the one or more electrodes to establish electrical contact between the one or more electrodes and a wall of the duodenum;
driving a current through the one or more electrodes; and
configuring the current to induce a contraction of the duodenum.

-
27. A method comprising:
driving a current into a duodenal site of a subject; and
configuring the current to enhance satiety of the subject by elevating a blood level of cholecystokinin (CCK) of the subject.
-
28. A method comprising:
driving a current into a duodenal site of a subject; and
configuring the current to enhance satiety of the subject by elevating a blood level of GLP-1 of the subject.

47. A method, comprising:
-
driving a current between first and second electrodes at respective first and second sites, spaced by at least 5 mm, of a duodenum of a subject; and
configuring the current to stimulate tissue in a longitudinal muscle layer of the duodenum.
-
-
48. A method, comprising:
-
driving a current between first and second electrodes at respective first and second sites, spaced by less than 5 mm, of a duodenum of a subject; and
configuring the current to stimulate tissue in a circular muscle layer of the duodenum.
