Block h6: imdrf device code a1502 captures the reportable event of stent first flange difficult to position.Imdrf device code a0501 captures the reportable event of tip detached.Block h10: an axios delivery system was returned for analysis.Visual examination of the returned device found the black marker damaged in the distal section, the outer sheath was bent, and the tip was detached and was not returned.No other problems were noted to the delivery system.Taking all available information into consideration, the investigation concluded that the reported event and observed failures were likely due to factors encountered during the procedure.It may be that lesion characteristics, how the device was handled, the technique used by the physician and/or normal procedural difficulties encountered during the procedure, limited the performance of the device and contributed to the reported event and the observed failures.The reported event of stent first flange difficult to position cannot be confirmed because this happened during the procedure and there is no bjective evidence or descriptive conditions to confirm the reported events.Therefore, a review and analysis of all available information indicated the most probable cause is adverse event related to the procedure.A labeling review was performed and, from the information available, this device was used per the instructions for use (ifu) / product label.
