An in vivo device, system and a method for imaging a body lumen, typically liquid filled body lumen. The in vivo device may have a specific gravity of about 1 or a volume to weight ratio that enables it to float. The in vivo device may include a sensor, for example an image sensor, and may be attached to or set in one or more buoyant bodies. The in vivo device may be moved through the body lumen by the liquid movement in that lumen. |
