ABSTRACT:
An endotracheal tube including a preformed inflatable plastisol balloon telescopically fitted over and secured to a forward end portion of a dual-lumen tube. The inflatable balloon is formed with an elongated forward collar which is fitted onto the dual-lumen tube. The tube and collar are simultaneously severed along a biased cut to provide an open front end of the endotracheal tube. The forward collar and dual-lumen tube are then fused into a generally homogeneous mass to provide a smooth exterior sliding surface at the forward end portion of the endotracheal tube.
