Abstract

A fixation device for holding stimulating electrodes in electrical contact with the wall of a portion of the gastrointestinal tract is provided. In one embodiment, the fixation device includes an expandable member that fixes the electrodes in electrical contact with the gastrointestinal tract wall. Also provided is an implantable device and method for controlling the opening and/or closing of the pylorus. In particular a device and method is provided for stimulating the duodenum to control the closing/and or opening of the pylorus. Finally, a method is provided for treating obesity by controlling the pylorus to retain food in the stomach for a desired period of time, among other things to provide a feeling of satiety and/or to reduce hunger. One aspect includes controlling the pylorus's contraction by electrical stimulation of the duodenum.
