An ingestible therapeutic device for the treatment of gastritis

An ingestible gastrointestinal phototherapy device comprising a spherocylindrical body of non-digestible material having a cylindrical midsection and transparent light portals at ends thereof, the cylindrical midsection comprising control circuitry and a power source therein and wherein each light portal is transparent and comprises an array of bioactive light source elements therein emitting bioactive light therefrom and being operably coupled to the control circuitry and power source and wherein the light source elements comprise an axial light source element orientated along a longitudinal axis of the spherocylindrical body and a plurality of radial light source elements around the axial light source element, each radial light source element orientated substantially orthogonally with respect to the longitudinal axis, having a cast angle of greater than 100° along the longitudinal axis and located within a respective portal such that light cast by radial light source elements from opposite ends of the body coincides at a midpoint having a perpendicular distance from the side of the cylindrical midsection being less than half and the distance between the longitudinally aligned radial light source elements.
