Brief Summary:
In this study, the feasibility of performing robotic navigation of peripheral airways in human subjects for the purpose of biopsying peripheral lung lesions will be evaluated.

Condition or disease Intervention/treatment Phase
Lung; Node Device: Robotic assisted bronchoscopy Not Applicable

Detailed Description:
Successful biopsy of peripheral pulmonary lesions remains a challenge due to a number of factors, one of which may be the ability to gain access to peripheral lesions due to the size and maneuverability of conventional bronchoscopes. In this study, the investigators will evaluate the feasibility of a new technique using a robotic endoscope with the Monarch navigational platform to both access and biopsy peripheral pulmonary lesions. The Monarch platform is a "robotic" assisted or electromechanical, software driven endoscopy system designed to be used by qualified physicians to provide bronchoscopic visualization of and access to patient airways for diagnostic and therapeutic procedures.

Primary Outcome Measures :
  1. Number of Participants With Device or Procedure Related Adverse Events [ Time Frame: 24-84 hours post-procedure ]
    Computed as the number of patients with device or procedure related adverse events divided by number of patients who underwent the robotic bronchoscopy procedure.

  2. Successful Navigation to Targeted Peripheral Pulmonary Lesions [ Time Frame: During the procedure, approximately 1 hour ]
    Successful navigation is confirmed using radial probe endobronchial ultrasound (R-EBUS). the R-EBUS will be inserted into the working channel of the endoscope and advanced beyond the tip of the inner scope as the inner scope is advanced into the lung periphery towards the targeted lesion. As the endoscope is guided towards the targeted lesion, R-EBUS will confirm successful lesion localization prior to biopsies being performed.


Secondary Outcome Measures :
  1. Incidence of Complications Unrelated to Device [ Time Frame: 24-84 hours post-procedure ]
    Computed as the number of patients with events unrelated to device or procedure divided by number of patients who underwent the robotic bronchoscopy procedure.

  2. Time to R-EBUS Confirmation (Lesion Localization) [ Time Frame: During the procedure, approximately 1 hour ]
    Defined by the time the robotic bronchoscope is inserted into the oropharynx until the localization of the targeted lesion is confirmed by REBUS.

  3. Total Procedure Time [ Time Frame: During the procedure ]
    Defined by the time the robotic bronchoscope is inserted into the oropharynx until the time a biopsy tool is removed.

  4. Diagnostic Yield [ Time Frame: Data was collected (as part of standard of care) through 1-year for calculation of diagnostic yield. ]
    Determined from the results of the bronchoscopy.
