Figure 1. — Photographs showing the method of EWS insertion using a cytology curette.

(A) A small cut was made with an 18-gauge injection needle at the thick end of the EWS to allow insertion of the tip of the curette. The tapered tip of a cytology curette could be inserted into the cut made on the tip of the EWS. (B) A curette equipped with an EWS could be rotated in any direction and bent at any angle. (C, D) Once the target bronchus was reached, the EWS was inserted into the bronchus, adjusting the angle and direction of the spigot. (E) After the EWS blocked the target bronchus, the curette was withdrawn while the EWS was pressed into the target bronchus with the bronchoscope.
