Abstract

Diet evaluation gastric apparatus (18) is provided, which detects when a patient (10) swallows, and detects the type and amount of matter ingested. The apparatus includes electrodes (74, 100) adapted to be coupled to the fundus and antrum of the patient and to measure electrical and mechanical activity therein, and a control unit (90) to analyze such electrical and mechanical activity and optionally apply electrical energy to modify the activity of tissue of the patient.

Claims

1. Gastric apparatus, comprising:

a gastrointestinal sensor, adapted to be coupled to a gastrointestinal site of a subject and to generate a gastrointestinal sensor signal responsive to a property of the gastrointestinal site;

a set of one or more antral sensors, adapted to be coupled to an antral site of an antrum of the stomach and to generate an antral sensor signal responsive to a property of the antrum; and

a control unit, adapted to receive an analyze the gastrointestinal and antral sensor signals, and to determine, responsive thereto, a characteristic of a food ingested by the subject.
