An endotracheal intubation device, optionally having a curvable portion and internal optics or a viewing device is provided. The curvable portion of a tubular element, over which is placed an endotracheal tube, curves in a controlled manner to a curved conformation from a straight or less curved configuration so as to facilitate the insertion of the endotracheal tube into a patient. A length of a proximal end of the tubular element projects over a grip portion of the device, which makes the device easier to use than other devices used for airway intubation.
