A tracheostomy tube introducer (1) has a patient end region (10) on which the tube (2) is mounted and that is curved in one sense. The introducer has a machine end region (11) projecting from the rear end of the tube (2) to provide a handle that curves in the opposite sense to the patient end region (10) so that the introducer has an S shape along its length. A bore (24) for a guide member extends from the patient end tip (14) of the introducer and opens in the machine end region (11) through a side opening (25). The introducer 1 is provided in a kit (200) with the tracheostomy tube (2) and a dilator (202) having the same general S shape as the introducer.
