Block h6: imdrf device code a0414 captures the reportable media analysis finding of stent barb torn.Block h10: the naviflex rx delivery system was returned for analysis.The advanix biliary stent was not received for analysis.Visual inspection found that the guide catheter was bent and the push catheter suture hole was torn.Media analysis of the photo of the stent inside the patient found that the stent barb was bent and torn; however, the suture was not visible.No other damages were noted with the delivery system.Product analysis confirmed the reported events of stent barb irregular shape, stent barb torn material, and user error; however, the reported event of suture break was not confirmed because it could not be observed during analysis.A labeling review was performed, and from the information available, this device was used in a manner inconsistent with the instructions for use (ifu)/product label.It was reported that the barb flap cover was not used to insert the device through the biopsy cap.Per the advanix biliary stent with naviflex rx delivery system instructions for use (ifu), "slide the outer orange sleeve over the most proximal stent barb to hold it down for stent insertion." thus, the user did not follow the manufacturer's instructions.Additionally, the investigation concluded that the deformed and torn stent barb and the additional investigation findings of the guide catheter being kinked and the push catheter suture hole being torn were most likely due to procedural factors such as lesion characteristics, the handling of the device, and the technique used by the physician.Therefore, taking all available information into consideration, the overall root cause of the reported event is adverse event related to procedure.
