1. A method for treating obesity in a patient, comprising the steps of:
- arranging at least one electrode on at least one of a pancreas, a pancreatic duct, a pancreatic sphincter, a bile duct, a cystic duct, a gall bladder, a biliary sphincter, or autonomic nerves supplying the pancreas and the biliary system, andactivating said electrode to provide an electrical stimulus thereto, wherein said electrical stimulus is configured to cause a dissociation between a timing of food passing through the intestinal lumen and a timing of at least one of pancreatic or biliary secretions and thereby cause or increase a disruption in said patient'"'"'s digestion of food.

Abstract
The present invention is directed to a method and apparatus for electrical stimulation of the pancreatico-biliary system. Electrode sets are placed in the pancreatico-biliary system in an arrangement that induce contractions or relaxation of the portion or whole of the pancreatico-biliary system by electrical stimulation of the surrounding tissue, muscles and nerves. The electrical stimulus is applied for periods of varying duration and varying frequency so as to produce the desired therapeutic effect, including inhibiting fat digestion or fat absorption by a patient and inducing satiety in the patient.

20. A device for electrical stimulation, comprising:
-
a pulse generator; and at least one electrode connected to the pulse generator wherein the electrode is arranged on at least one of a patient'"'"'s pancreas, pancreatic duct, pancreatic sphincter, bile duct, gall bladder, biliary sphincter, or autonomic nerves supplying the pancreas, such that activating said electrode is effective to treat obesity in said patient by delivering an electrical stimulus configured to cause a dissociation between a timing of food passing through the intestinal lumen and a timing of at least one of pancreatic or biliary secretions and thereby causing or increasing an inhibition of at least one of fat digestion or fat absorption in said patient.
