ABSTRACT:
A tracheostomy tube assembly has an outer catheter and an inner cannula that is insertable into and removable from the outer catheter. The inner cannula has two elongate regions along its length of different flexibility. The main body of the cannula may be relatively stiff and a narrow region along its length be of a more flexible material, such as extruded to form the entire thickness of the wall of the cannula, so that the cannula is preferentially flexible in the plane of the center line of the narrow region to permit the cannula to be inserted, without kinking or buckling, into the outer catheter.
