ABSTRACT:
A catheter formed of an elongated, hollow tube having a sealed, separate air passageway formed integrally of the tube and extending from a point near the forward end of the tube to an integral air inlet nozzle located near the rear end of the tube and extending outwardly therefrom. An inflatable barrel shaped cuff is mounted upon and encircles the tube near its forward end, there being an opening in the tube wall communicating the interior of the cuff with the air passageway for inflating and deflating the cuff. A cup shaped seal is also mounted upon the tube and is frictionally secured thereto by integral springy flanges which permit forwardly sliding the seal upon the tube but which resists rearward sliding of the seal.
