Mallinckrodt GmBH developed the disposable endotracheal tube and produced a plethora of design variations, adding the 'Murphy Eye' to their tubes in case of 'accidental' placement of the tube to avoid right bronchial occlusion. David S. Sheridan was one of the manufacturers of the American markets "disposable" plastic endotracheal tube now used routinely in surgery. Previously, red rubber (Rusch-Germany) tubes were used, then sterilized for re-use.
