2020-151 ENDOBRONCHIAL CATHETERS

SUMMARY Bronchoscopy has been used in the past to visualize the endobronchial lumen and to direct diagnosis, treatment, or medication. Unfortunately, most bronchoscopy systems are very operator-dependent and lack the necessary guidance and targeting needed for specific localization. In recent years navigation systems are used to direct the bronchoscope...
