A disposable mini-endoscope (KinCam) with six LED lights and a mini-camera at the tip was placed in the internal channel of VL blades. It was connected either to a laptop computer or an Android cell phone to display airway images (Fig. 3 D-F and Fig. 5 A,B). A 5.5 mm diameter mini-endoscope was used in larger blades for adults whereas a 3.8 mm endoscope was used for pediatric blades (Fig. 4 C). All VLs were tested in adult and pediatric intubation manikins FIG 2 between the upper incisors and the epiglottis. The 2-D drawings were transferred to the Autodesk Auto CAD (Fig. 3 D). The mini-endoscopes generated very sharp and bright images of the glottis (Fig. 3 E). The VL blade angulation allowed an easy placement of the endotracheal tube (Fig. 3 F). program (Fig. 2A) which allowed a 3-D rendering of the airway anatomy and design of the VL blade with customized shape, length and blade angulation (Fig. 3 A-C). The blade design included an internal duct for the placement of a mini-endoscope. The VL blade was manufactured (Fig. 2 B-D) using the Axiom 3-D printer which used ABS printing material.2,3 FIG 4 Endotracheal intubation in patients with difficult airway anatomy is sometimes impossible with the use of fixed blades. A supraglottic airway (SGA) can be used as a bridge to intubation with a fiberoptic scope. Using the same 3-D design and printing technique FIG 3 as described for VLs, we developed4 a customized intubating supraglottic airway (iSGA). The mini- 2 Wojtczak J. Videolaryngoscope on Demand.
