After a wire crossed the lesion, the 8mm x 150mm smart control self expanding stent (ses) was inserted however, it was difficult to deliver to the lesion.Therefore, it was removed from the patient¿s body and the physician found out that the distal end of the tip was frayed.The device was replaced with a new smart stent and the procedure was completed.There was no reported patient injury.The lesion was the iliac artery.The device will not be returned for evaluation as it discarded due to infectious disease.

After further review of additional information received the following sections g4, g7, h2 and h6 have been updated accordingly.After a wire crossed the lesion, a smart control 8 mm x 150 mm self expanding stent (ses) was inserted however, it was difficult to deliver to the lesion.Therefore, it was removed from the patient¿s body and the physician found out that the distal end of the tip was frayed.The device was replaced with a new smart stent and the procedure was completed.The lesion was the iliac artery.There was no reported patient injury.Additional procedural details were requested but are unknown.The device was not returned for analysis.A product history record (phr) review of lot 17884441 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.Without the return of the device for analysis and based on the limited information provided, the reported ¿catheter tip- frayed/split/torn - in patient¿ could not be confirmed and the exact root cause could not be determined.Handling and or procedural factors such as vessel characteristics (although unknown) may have contributed to the reported event.According to the instructions for use, which are not intended as a mitigation of risk, ¿after careful inspection of the pouch looking for damage to the sterile barrier, carefully peel open the pouch and extract the stent delivery system from the tray.Examine the device for any damage.If it is suspected that the sterility or performance of the device has been compromised, the device should not be used.Evaluate the distal end of the catheter to ensure that the stent is contained within the outer sheath.Do not use if the stent is partially deployed.Advance the device over the guide wire through the hemostatic valve and sheath introducer.Note: if resistance is met during delivery system introduction, the system should be withdrawn, and another system should be used.¿ neither the phr review nor the information available suggests a design or manufacturing related cause could be related to the manufacturing process of the unit.Therefore, no corrective or preventive actions will be taken.
