One or more ducts or chambers are formed between the outer surface of the inner tube and the inner surface of the outer tube. A sealing or mounting flange is attached to the composite tube adjacent one thereof. A balloon or inflatable cuff is attached to the outer surface of the outer tube adjacent the opposite end of the composite tube. A conduit for connection to a fluid source is provided to selectively inflate and/or deflate the inflatable cuff. An inner tube or cannula is removably inserted into the tracheostomy tube. The inner cannula includes a preferred gripping device at the proximal end thereof.
