Manufacturer Narrative

It was reported that stent cell was broken based on complaint description received.However, no cell was broken and it was only loosen as a result of our analysis with returned device.It is impossible to identify the exact root cause since it is hard to recreate the situation at the time of procedure.However, it is considered that stent cell was loosen since removal of delivery system was tried after deployment without placing inner sheath back into outer sheath by user based on complaint description.It is specified on our user manual as follows in order to prevent these problems.It should be careful when removing the introducer system and guidewire after stent deployment.And if it is felt excessive resistance during removal of them, wait 3-5 minutes to allow further stent expansion.(place the inner sheath back into the outer sheath as the original state prior to removal.)" also no defect on device history record was found since 100% sampling inspection was performed during process inspection in order to check tip was properly adhered on its inner sheath.It will be monitored that similar case is occurred from now on.The suspected device is not registered to us fda and it has not been shipped into the us.
