Manufacturer Narrative

Block a2: the patient's exact age is unknown; however, it was reported that the patient was over the age of 18.Block h6: imdrf device code a1502 captures the reportable event of a stent positioning issue.Block h10: the ultraflex esophageal ng proximal covered stent and delivery system were received for analysis.Visual investigation found that the stent was fully expanded and deployed from the delivery system, and the shaft was kinked.No other damages were noted with the stent or the delivery system.Product analysis did not confirm the reported event of the stent positioning issue because this event occurred during the procedure and was not possible to replicate in the laboratory of analysis, and there was no objective evidence or descriptive conditions to confirm the reported event.Additionally, the investigation concluded that the additional finding of shaft kinking was most likely due to procedural factors such as lesion characteristics, the handling of the device, and the technique used by the physician (force applied), which could have resulted in the damage encountered in the device.Therefore, a 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.
