Overall diagnostic yield (concentric and eccentric lesions) for peripheral pulmonary nodules
-To determine overall diagnostic yield (concentric and eccentric lesions) for peripheral pulmonary nodules utilizing using a standard of care combined approach of 4mm thin and 3mm ultrathin bronchoscopes with TBNA and radial EBUS and compare it to a historical baseline diagnostic yield of 60% established at Washington University School of Medicine (WUSM) when using TBNA and radial EBUS and a 4mm thin bronchoscope.
Time frame: Receipt of cytology/histopathology results (approximately 7 days)
Incidence of related adverse events
-Adverse events related to the bronchoscopy procedure and/or devices used during the procedure (bronchoscope, radial EBUS, PeriView Flex needle).
Time frame: Up to 4 days following procedure
Procedure time measured in minutes from oral scope insertion to scope removal upon completion of the bronchoscopy procedure
Time frame: From start of procedure through end of procedure (day 1)
Size of target lesions measured at the greatest diameter in centimeters
Time frame: From start of procedure through end of procedure (day 1)
Diagnostic yield of bronchoscopy utilizing a 3mm bronchoscope for eccentric lesions
-Will be compared with historical controlled data of cases in which peripheral bronchoscopy was performed for peripheral lesions using radial probe EBUS and a 4mm bronchoscope in which eccentric ultrasound views were obtained
Time frame: Receipt of cytology/histopathology results (approximately 7 days)
Ability to successfully convert ultrasound images from eccentric to concentric view by exchanging the 4mm thin bronchoscope for the 3mm ultrathin bronchoscope

* NA-403D-2021 * Gyrus ACMI, Inc.
-The ability to convert will be based on the ultrasound image that is obtained using the 3mm bronchoscope (it will either be eccentric or concentric) compared to the eccentric ultrasound image obtained with the 4mm bronchoscope
Time frame: From start of procedure through end of procedure (day 1)
Types of deficiencies associated with medical device
Time frame: From start of procedure through end of procedure (day 1)
