Patent ID: 8474459

Claim:
A device having a guide catheter for the introduction of a tracheal cannula into a tracheostoma, characterised in that the guide catheter has a shield which is mounted in the proximity of the distal end of the guide catheter and which shield comprises a flexible material which is substantially in the form of a distally directed conical tip, wherein the tube of the guide catheter passes through the axis of said tip to extend there beyond, with a base outside diameter which in a first state approximately corresponds to the outside diameter of the tracheal cannula and in a second state by deformation is smaller than the inside diameter of the tracheal cannula and is thus retractable through the tracheal cannula, whereby a displacement body in the form of a hollow cylinder, the outside of which is smaller than the inside diameter of the cannula and which can be pushed on over the guide catheter in the cannula is in engagement with an inside surface of the shield in the first state, which displacement body can be withdrawn from the guide catheter and cannula leaving the guide catheter and the shield in place in respect to the cannula.
