A smart control 7 x 60 self-expanding stent delivery system was delivered along the non-cordis guidewire; however, it got stuck in the non-cordis guiding sheath.The doctor pulled its handle and tried to remove it; however, the stent was deployed in the guiding sheath.Therefore, all devices were removed from the patient body and the procedure was interrupted.A brachial approach was made with a 6f non-cordis guiding sheath.A 0.014¿ non-cordis guidewire was delivered into the left iliac artery.Another 0.035¿ non-cordis guidewire was delivered into the right iliac artery.Additional procedural details were requested but are unknown.There was no reported patient injury.The device was not returned for analysis as it was discarded.A product history record (phr) review of lot 17910528 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 delivery system (sds)-ses~ deployment difficulty - premature/in patient - during withdrawal¿ could not be confirmed and the exact root cause could not be determined.Handling and procedural factors such as vessel characteristics (although unknown) and the user¿s interaction during withdrawal of the device may have led to the reported events.According to the instructions for use ¿if resistance is encountered at any time during the insertion procedure, do not force passage.Resistance may cause damage to the stent or lumen.If resistance occurs during movement through the sheath, carefully withdraw the stent system.If resistance is felt when initially retracting the outer sheath, do not force deployment.Carefully withdraw the stent system without deploying the stent¿.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.
