A stylet and method of use to intubate a subject. The stylet includes a malleable rod removably housed within the stylet, as well as a flexible proximal portion having a predetermined shape defined by the malleable rod when inserted in the stylet, and a distal tip, wherein the distal tip is capable of deflection when the malleable rod is inserted in the stylet. The stylet further includes a manually operable actuator configured to receive a force from a user at the proximal end of the stylet to control a deflection angle of the distal tip.
