A selective tracheal bronchial catheter is provided with a double bend at the distal end and means for twisting the catheter around its longitudinal axis at its proximal end. Thus, the surgeon can selectively cause the tip of the catheter to enter the left main bronchus and upper lobar bronchus without fluoroscopy. Slight withdrawal and 15 DEG twist guides the tip into the left lower lobar bronchus. Slight withdrawal and 180 DEG twist guides the tip into the right main bronchus. Markings on the catheter indicate the degree of twist of the double bend and the distance of insertion. A concentric irrigation tubule, of different material, irrigates and dislodges phlegm, well in advance of the suction tip of the catheter, and self cleans the catheter tip opening. |
