A stylet is disclosed for insertion into an endotracheal tube for guiding the tube during intubation. The stylet has a body (3) with a pivotable tip portion (5) at its distal end which is movable in either of two opposing directions away from the axis of the stylet. The tip portion (5) may carry an image acquisition device for video imaging. A control mechanism for controlling the pivot angle of the pivotable tip has a hand-operated actuator (7) at the proximal end of the stylet and flexible control wires (23) extending down the stylet to connect the actuator to the pivotable tip portion (5). Also disclosed is an endotracheal tube (100) usable with the stylet and having a bending portion (103), defined by a concertina or thinned portion, at its distal end to facilitate bending of its tip portion (104) by the stylet tip portion (5).
