Broncus Medical Inc., of San Jose, Calif., is highlighting data that it says shows that the Archimedes virtual bronchoscopy navigation system significantly improves access to solitary pulmonary nodules (SPN). The company noted that the system helps increase the diagnostic yield for nodules without a bronchus sign or an airway leading to the nodule. The data were unveiled at the European Respiratory Society (ERS) International Congress being held in Paris this week.
