Gastrointestinal stimulation device

A method for controlling a contraction of a pylorus comprising the steps of:

• providing a stimulator comprising:
• a fixation device;
• at least one electrode coupled to the fixation device;
• and
• electronic circuitry coupled to the at least one electrode and configured to deliver electrical stimulation through the at least one electrode;
• positioning the fixation device in the duodenum of a patient so that the at least one stimulating electrode is in electrical contact with the wall of the duodenum;
• providing stimulation pulses from the electronic circuitry to the duodenum through the at least one electrode and thereby affecting the contraction of the pylorus.

A gastrointestinal stimulation device comprising:

• a fixation device comprising at least one electrode coupled to the fixation device, wherein the fixation device is configured to be positioned within a portion of an intestinal tract so that the at least one electrode is in electrical contact with the intestinal tract, and so that matter may be transmitted through the portion of the intestinal tract;
• an electronic housing configured to be positioned in the stomach;
• and
• wherein the electronics housing comprises electronics unit in electrical communication with the at least one electrode, wherein the electronics unit is configured to supply electrical stimulation pulses to the intestinal tract through the at least one electrode.
