Abstract: An ingestible capsule arranged, in use, to cross a human stomach for carrying out a phototherapeutic treatment arranged to combat an infection due to the presence of the bacterium Helicobacter pylori, the ingestible capsule comprising at least one primary light source arranged to emit an electromagnetic phototherapeutic wave having a wavelength ?1, at least one auxiliary light source arranged to emit an electromagnetic phototherapeutic wave having a wavelength ?2, a wrapper arranged to contain the or each primary light source and the or each auxiliary light source, the wrapper being at least partially transparent to the wavelengths ?1, and ?2, a control unit arranged to selectively activate the or each primary light source and/or the or each auxiliary light source.

Abstract: An ingestible capsule arranged, in use, to cross a human stomach for carrying out a phototherapic treatment arranged to combat an infection due to the presence of the bacterium Helicobacter pylori, said ingestible capsule comprising at least one primary light source arranged to emit an electromagnetic phototherapic wave having a wavelength ?1, at least one auxiliary light source arranged to emit an electromagnetic phototherapic wave having a wavelength ?2, a wrapper arranged to contain said or each primary light source and said or each auxiliary light source, said wrapper being at least partially transparent to said wavelengths ?1 and ?2, a control unit arranged to selectively activate said or each primary light source and/or said or each auxiliary light source, and at least one energy source arranged to provide energy for feeding said control unit and/or said light sources. In particular, 400 nm<?1<525 nm and 525 nm<?2<650 nm.
