First Claim
Patent Images
1. A device for electrical stimulation of a gastrointestinal tract of a patient, the device comprising:
- a device housing sized for introduction into a gastrointestinal tract;
an electrical pulse generator, mounted within the device housing, to generate an electrical stimulation waveform;
one or more electrodes electrically coupled to the electrical pulse generator and mounted to the device housing to deliver the electrical stimulation waveform to the gastrointestinal tract; and
a fixation structure to attach the device housing to a surface within the gastrointestinal tract.

Abstract
An intra-luminal device for gastrointestinal electrical stimulation is self-powered and self-contained within a capsule-like housing, and is capable of non-surgical implantation within the patient. The device includes an implantable pulse generator and one or more electrodes mounted within a common device housing. The device housing is capable of endoscopic introduction to a desired location within the gastrointestinal tract, such as the stomach, via the esophagus. The device may be appropriate for short-term, mid-term or trial stimulation applications.
