An intubation assembly rod in combination with an endotracheal tube insertion device has an elongated insertion member and is configured for insertion into an endotracheal tube, such that the endotracheal tube is carried thereon. The intubation assembly rod includes an elongated body having a distal end and a proximal end. The distal end of the intubation assembly rod body is tapered, rounded, or spherical and defines a leading end of the intubation assembly rod. The intubation assembly rod includes a longitudinally extending channel configured such that an elongated member of a flexible optical assembly may be inserted into the channel. The flexible optical assembly member has an elongated body having a substantially cylindrical shape and a plurality of longitudinally extending conduits formed therein configured to have one or more of a first video imaging device or a first light source disposed therein.
