As reported, after the 8mm x 40mm x 120cm smart control self-expanding stent (ses) system was placed, it was found that the stent had shortened.There was no reported patient injury.The product was stored properly per the instructions for use (ifu).There was no reported difficulty removing the product from the packaging.There was no damage noted on the device before or after the procedure.There were no anomalies nor difficulties noted while using the smart stent.The target lesion for the procedure was the femoral artery.A femoral approach was used for the procedure.There was no unusual force used at any time during the procedure.A 6f cordis sheath introducer was used.A guiding catheter was used.The diameter of the unconstrained stent size was 1-2 mm larger than the vessel diameter.The stent was not thought to be too short due to compression (after deployment in the patient).An additional stent was implanted in the patient due to the reported product issue.The procedure was completed successfully without patient injury.The device will be returned for analysis.

Complaint conclusion: after the smart control 8mm x 40mm x 120cm self-expanding stent (ses) system was placed, it was found that the stent had shortened.The product was stored properly per the instructions for use (ifu).There was no reported difficulty removing the product from the packaging.There was no damage noted on the device before or after the procedure.There were no anomalies nor difficulties noted while using the smart stent.The target lesion for the procedure was the femoral artery.A femoral approach was used for the procedure.There was no unusual force used at any time during the procedure.A 6f cordis sheath introducer was used.A guiding catheter was used.The diameter of the unconstrained stent size was 1-2 mm larger than the vessel diameter.The stent was not thought to be too short due to compression (after deployment in the patient).An additional stent was implanted in the patient due to the reported product issue.The procedure was completed successfully without patient injury.There was no reported patient injury.The device was not returned for analysis.A product history record (phr) review of lot 17901050 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 information provided, the reported ¿stent-ses~ incorrect length - too short¿ could not be confirmed and the exact root cause could not be determined.Handling and procedural factors such as vessel characteristics (although unknown) and or the user¿s interaction with the device may have led to the reported event.The instructions for use (ifu) advises that during placement, it is imperative that the treating physician holds the deployment handle in a fixed position during the entire deployment.If the handle is moved forward or backward after the stent has achieved initial wall apposition then segments of compression or expansion can be created.This can result in stent lengths which are longer or shorter than expected.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.
