ABSTRACT:
An apparatus and method is disclosed for an improved multi-tubed catheter for physically dislodging and removing material from a lung by suction and simultaneously aerating the lung with oxygen. The catheter comprises an oxygen tube for conveying oxygen into the lung, a suction tube adapted to remove material from the lung and an inflation tube for inflating a small balloon for separating the flow of oxygen from the suction. As the multi-tubed catheter is moved through the lung, the balloon mechanically dislodges material from the lung to be conveyed out of the lung through the suction tube. The lung is contiuously ventilated by oxygen during the removal process.
