The NaviAid™ G-Eye™ is a unique balloon endoscope with the world's only re-usable balloon. The balloon is located at the bending section of the endoscope, and is an integral part of the endsocope. The G-Eye™ endoscope, together with the NaviAid™ AB through-the-channel balloon device, provide an unltimate assembly for performing deep and swift two-balloon endoscopy while avoiding the limitations of the other balloon techniques. With the NaviAid™ G-Eye™ there is no need for mounting and pre-procedure preparation, no over-tube usage and no extended learning process. The NaviAid™ G-Eye™ and the NaviAid™ AB are controlled by the NaviAid™ SPARK²  which controlls two balloons.
