During the advancement of a smart control 8mm x 100mm 120 self-expanding stent (ses) delivery system, it was noted that the head of the device was damaged.The tip of the sheath catheter was "bifurcated", split during advancement into the lesion.The procedure was completed using another unknown stent.The temperature exposure indicator on the pouch was checked to confirm that the black dotted pattern with a grey background is clearly visible.The product was stored and handled according to the instructions for use (ifu).The product was inspected and prepped according to the ifu.There was nothing unusual noted about the stent delivery system prior to use.The unknown intended lesion was not located at the carotid bifurcation.A 6f non cordis sheath introducer was used using an ipsilateral approach.There was no guide catheter used.The unknown target lesion had 50% stenosis with mild calcification and no tortuosity.The stent delivery system did not pass through any acute bends.There was no reported patient injury.The device was not returned for analysis.A product history record (phr) review of lot 17950861 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported events.Without the return of the device for analysis the reported catheter tip~ frayed/split/torn - in patient was not confirmed.It is difficult to draw a clinical conclusion between the device and the events based on the information available.However, it is probable that procedural and or handling factors such as the user¿s interaction with the device and vessel characteristics (50% stenosis with mild calcification) may have contributed to the reported event.According to the instructions for use (ifu) ¿ensure locking pin is still in place.Note: if the locking pin is not in place, system performance may be compromised, and another system should be used.Advance the stent delivery system over the guidewire through the sheath introducer to the lesion site.Note: if resistance is met during delivery system introduction, the system should be withdrawn and another system should be used.Caution: always use an appropriate size introducer sheath for the implant procedure to protect vessel and access site.¿ 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.
