As reported by the physician, the 9x40 smart control iliac stent seemed to jump forward more than was normally expected.The stent migrated approximately 3-4 cm.The stent was left in place in the patient.Additional stents were not needed to complete the procedure; the surgeon stopped further interventions after stent failure.There was no reported patient injury.The device was opened in sterile filed and stored as per labeling.The intended procedure was reported to be an angiogram, angioplasty with stent placement.There was no significant calcification or tortuosity noted with seventy percent (70%) stenosis and thirty percent (30%) post-angioplasty.The area was predilated prior to stent implantation using a non-cordis balloon.The device was handled, and prepped per the instructions for use (ifu) and there was no difficulty experienced in prepping the device.There was nothing unusual noted about the stent delivery system prior to use.The stent was still constrained within the outer sheath when it was removed from the tray.The diameter of the unconstrained stent was sized 1-2 mm larger than the target area.There was no resistance/friction during insertion of the device.The stent delivery system did not pass through any acute bends.There was no difficulty encountered while advancing/tracking the sds towards the lesion.No unusual force was used at any time during the procedure.The device is expected to be returned for investigation.

As reported by the physician, the 9x40 smart control iliac stent seemed to jump forward more than was normally expected.The stent migrated approximately 3-4 cm.The stent was left in place in the patient.Additional stents were not needed to complete the procedure; the surgeon stopped further interventions after stent failure.There was no reported patient injury.The device was opened in sterile filed and stored as per labeling.The intended procedure was reported to be an angiogram, angioplasty with stent placement.There was no significant calcification or tortuosity noted with seventy percent (70%) stenosis and thirty percent (30%) post-angioplasty.The area was predilated prior to stent implantation using a non-cordis balloon.The device was handled and prepped per the instructions for use (ifu) and there was no difficulty experienced in prepping the device.There was nothing unusual noted about the stent delivery system prior to use.The stent was still constrained within the outer sheath when it was removed from the tray.The diameter of the unconstrained stent was sized 1-2 mm larger than the target area.There was no resistance/friction during insertion of the device.The stent delivery system did not pass through any acute bends.There was no difficulty encountered while advancing/tracking the sds towards the lesion.No unusual force was used at any time during the procedure.The device was returned for analysis.A non-sterile unit of product ¿smart control, iliac 9x40¿ was received coiled inside of a clear plastic bag.The part was unpacked to perform the evaluation.The stent of the unit was already deployed.One kinked/bent condition was observed located approximately at 76 cm from the distal end.No other damages or anomalies were observed at the inspected device.Even though the device was received already deployed, functional analysis was performed to determine the functionally of the unit.The turning dial was rotated with the thumb in a clockwise direction (direction indicated by the arrow).The turning dial was continuously turned until the distal section of the stent was totally deployed.No anomalies were observed during this process.A product history record (phr) review of lot 18187442 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿stent delivery system (sds)- deployment difficulty¿ was not confirmed since no anomalies were noted during the functional test.In addition, the device was received already deployed.However, the complaint can be confirmed as stent delivery system (sds)-kinked-bent since this condition was found at the outer shaft, it is possible that this condition may have caused the reported issue.The reported ¿stent-migration¿ was not confirmed since it is not possible to determine what may have caused the reported issue due to the nature of the complaint.According to the instructions for use (ifu) ¿if resistance is encountered at any time during the insertion procedure, do not force passage.Resistance may cause damage to stent or system.If resistance occurs during movement through the sheath, carefully withdraw the stent system.Once stent deployment has begun, the stent must be fully deployed.The system is not designed for stent repositioning or recapturing.If resistance is felt when initially retracting the outer deployment sheath do not force deployment.Carefully withdraw the stent system without deploying the stent.¿ neither the phr review, nor the product analysis suggests that the found damages could be related to the manufacturing process of the unit.Therefore, no corrective or preventive actions will be taken at this time.
