| abstract |
A tracheostomy tube assembly includes an outer tracheostomy tube ( 1 ) and a removable inner cannula ( 3 ). The inner cannula ( 3 ) is made by helically winding PTFE tape ( 40 ) on a mandrel ( 42 ) and applying a reinforcing strip ( 34 ) of PTFE or other materials longitudinally along the outside of the wound tape. The tape and strip are then heated to sinter and bond them together and convert the PTFE to ePTFE and form an inner layer. An outer layer ( 46 ) is extruded along the outside of the inner layer. The shaft ( 30 ) is cut between the ends of adjacent reinforcing strips ( 34 ) to leave a short unreinforced portion ( 35 ) at the patient end ( 32 ) of each shaft. |
