An introducing stylet is configured for insertion into an endotracheal tube (ETT) and includes an elongated rod having a distal end and a proximal end, and a positioning feature formed on the rod and configured to engage the ETT to prevent both longitudinal and lateral movement of the introducing stylet relative to the ETT. A portion of the distal end of the rod that extends longitudinally outwardly of the ETT and defines a leading end.
