Product Description Callisto is the U.K’s No.1 single use laryngoscope system. It has been designed to offer a true low cost alternative to reusable blades and handles with exceptional specifications and clinical performance. The blades feature a reduced height profile to provide better visualisation and easier access for small mouth openings, as well as minimising the possibility of dental damage. Our 4mm light guide is specially manufactured to resist deforming or breaking under normal use yet provides optimum light transmission, especially when combined with our powerful Xenon, XLED and our Callisto LED handles.
