Method and Apparatus for Electrical Stimulation of the Pancreatico-Biliary System
First Claim
1. A method for treating a biological condition, 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, and activating said electrode to provide an electrical stimulus thereto.

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) a pulse generator; and
b) at least one electrode set connected to the pulse generator wherein the electrode sets are arranged on at least one of a pancreas, a pancreatic duct, a pancreatic sphincter, a bile duct, a gall bladder, a biliary sphincter, or autonomic nerves supplying the pancreas and biliary system, such that activating said electrode is effective to modulate secretions of biliary or pancreatic juices.
- a) a pulse generator; and
