Abstract

In-vivo devices, systems and methods can be for the detection of blood within in-vivo fluids. The in-vivo devices include a gap or passage, which remains in contact with bodily fluids, and through which the fluids pass when the device is in-vivo. The devices further include illumination sources on a first side of the gap or passage for irradiating in-vivo fluids that pass through the gap or passage. The devices further include a light detector positioned on a second side of the gap/passage opposite to the first side and facing the illumination sources, for detecting light from the illumination sources that passes through the in-vivo fluids.
