ABSTRACT:
The present invention relates to a tubular assembly which can be intubated within a body passageway which comprises a main tube body, which permits the passage of fluid in either direction (such as air in the case of an endotracheal tube), an inflatable cuff near the distal end of the main tube body for locating and securing the tubular assembly within a body passageway as well as for sealing the space above the cuff between the main tube body and the body passageway from the body passageway below the cuff, and a suction tube that runs along the main tube body from the proximal end that remains external of the patient during intubation and a point adjacent the inflatable cuff. The suction tube is fixed with the main tube except for an adjustable portion of the suction tube nearest the inflatable cuff that includes the suction tube opening. The adjustment portion of the suction tube is free to move relative to the main tube body such that it is selectively radially adjustable in position to or from the main tube body. Moreover, the adjustable portion of the suction tube is movable by an adjustment balloon positioned between the adjustable portion of the suction tube and the main tube body. Furthermore, the adjustment balloon is selectively inflated or deflated for radially moving the adjustable portion between an innermost position in close proximity to the outer surface of the main tube body, and an outermost position wherein the adjustable portion and suction tube opening are in close proximity to the wall of the body passageway.
