An articulating stylet usable with a tracheal intubation system is disclosed. Methods for using the articulating stylet and systems that incorporate the articulating stylet are also disclosed. In some examples, a stylet adapted for mounting an endotracheal tube comprises a shaft and a control wire. The shaft comprises a distal shaft portion, a proximal shaft portion, and an expanding connection joining the distal shaft portion to the proximal shaft portion. The proximal shaft portion has a body portion and a tip portion. The tip portion includes a tip and has greater flexibility than the body portion. The control wire is at least partially disposed within both the distal shaft portion and the proximal shaft portion and is configured to cause the tip portion of the proximal shaft portion to deform.
