AbstractA stylet for use in both oral and nasal endotracheal intubation comprises a flexible member, a collar slidably mounted thereon, a handle mounted at one end of and along the longitudinal axis of the flexible member and a fixed length filament attached to a distal end of the flexible member and the collar. A portion of the stylet is telescopically received within an endotracheal tube. The user may selectively deflect or induce curvature to the endotracheal tube by applying force to the handle along the axis of the flexible member and inducing movement of the handle with respect to the collar when the filament is under tension. Alternatively, the user may selectively deflect the endotracheal tube by inducing movement of the collar with respect to the handle when the filament is under tension.
