A tracheostomy airway device 100 comprising an outer cannula 110 having open proximal and distal ends, an inner actuation member 120 insertable into the proximal end of the outer cannula, and one or more retention members 130. The one or more retention members 130 are movable relative to the outer cannula 110 between a retracted configuration in which the tracheostomy device 100 is insertable into, and removable from, the trachea of a patient and an extended configuration in which the one or more retention members 130 impede removal of the device 100 from the trachea. The retention members 130 are operably linked to the inner actuation member 120 or the outer cannula 110. Such that movement of the inner actuation member 120 relative to the outer cannula 110 actuates movement of the one or more retention members 130 between the retracted configuration and the extended configuration. The inner actuation member may form an inner cannula. The retention members 130 may be subject to a biasing force. The retention members 130 may be connected to the outer cannula 110 or inner actuation member 120 by a mechanical connection. A method for inserting the tracheostomy airway device 100 is also provided.
