Manufacturer Narrative

Block h6: imdrf device code a150101 captures the reportable event of stent failure to expand.Imrdf device code a1502 captures the reportable event of stent positioning issue.Block h10: the ultraflex tracheobronchial covered distal stent and delivery system were received for analysis.Visual inspection revealed that the stent was fully expanded and deployed and that the shaft was kinked.No other issues were noted with the delivery system.Product analysis revealed the shaft was kinked which was most likely due to procedural factors such as lesion characteristics, handling of the device, or the techniques used by the user.However, product analysis did not confirm the reported device malfunction of stent failed to expand as the stent was returned fully deployed and expanded.The reported failure of stent positioning issue cannot also be confirmed because this happened during the procedure and is not possible to replicate in the laboratory for analysis.There is no indication of what the customer reported because the stent was returned completely expanded.Therefore, review and analysis of all available information indicated that the most probable cause is no problem detected.A product labeling review identified that the device was used per the instructions for use (ifu)/product label.
