Abstract
The invention relates to an in vivo sensing device having a specific gravity of about 1 or a volume to weight ratio that enables it essentially to float. In one embodiment the in vivo sensing device consists of an image sensor system and a buoyant body. The buoyant body, which is attached to the sensor system or which can optionally house one or more elements of the sensor system, keeps the sensor system essentially floating in a body lumen liquid.
