ITS: Inductive Tracking System for Gastrointestinal Motility Diagnosis

Résumé des résultats (Abstract) (Anglais)

Digestive functional troubles like constipation, gastroparesis and dyspepsia affect more than 20% of the population. Up to now the diagnostic techniques are very limited and invasive. We propose an ingestible minimally-invasive capsule whose position and orientation can be accurately measured. A lot of information about the motility (mechanical activity) can be extracted from the capsule movements: intrinsic rhythmic activity, displacement of the content and the anatomy of the digestive tract. The capsule made of a coil, a circuit and a battery emits an alternative magnetic field. An external array of coils maps the magnetic field distribution and allows calculating the position and the orientation of the capsule.
