Patent ID: 7330753

Claim:
A method for analyzing gastric function of a stomach of a subject, comprising: coupling a gastrointestinal sensor to a gastrointestinal site of the subject, and sensing a property of the gastrointestinal site using the gastrointestinal sensor; coupling a set of one or more antral sensors to an antral site of an antrum of the stomach, and sensing a property of the antrum using the set of one or more antral sensors; analyzing the property of the gastrointestinal tract and the property of the antrum; and determining, responsive to the analysis, a characteristic of a food ingested by the subject, wherein sensing the property of the gastrointestinal tract comprises sensing a property of a fundus of the stomach, wherein sensing the property of the fundus comprises sensing an electrical current in the fundus, and wherein sensing the property of the antrum comprises sensing an electrical current in the antrum, and wherein sensing the current in the fundus comprises sensing a current indicative of a measure of electrical impedance between two sites of the fundus.
