Manufacturer Narrative

Section b1 adverse event/product problem - corrected - no product problem.Section h1 type of reportable event - corrected - no malfunction.Due to the automated mes (manufacturing execution system) system there are controls in the manufacturing process to ensure the product met specifications upon release.During visual inspection, the returned stent was found to be opened but severely deformed, the sdw (stent delivery wire) was not returned, and the stent introducer sheath was not returned.A functional test could not be performed as only the stent was returned for inspection.The reported event is covered in the device directions for use (dfu).As well, the risk of the reported event is documented in the risk documentation and there are current controls to mitigate the risk of the as reported event.The reported complaint was not confirmed based on analysis.The device failed to meet specification when received for complaint investigation based on the analyzed anomaly noted to the device.Additional information provided by the customer indicated that there was no damage noted to the packaging prior to preparation of the device, the device was confirmed to be in good condition prior to use, preparation/set-up was performed as per the directions for use, there was no damage noted on the stent or the stent delivery wire (sdw), continuous flush was maintained for the duration of the procedure, no excessive force was applied at any point while advancing the stent/flow diverter within the microcatheter and the patient¿s anatomy was tortuous.It is unknown if access was through radial or femoral.The anatomical location of the treatment site was cavernous ics and it was also the location of the stent/flow diverter when it failed to open.The catheter tip was not shaped.The stent delivery microcatheter was retracted in a continuous movement while maintaining the position of the stent delivery wire, the size of the stent/flow diverter was appropriate for treatment site and the position of the stent/flow diverter was confirmed under fluoroscopy.There was no resistance encountered during navigation of the flow diverter device to the target lesion.The flow diverter was apposed distally but not proximally, it was not fully deployed.There were no allegations against the microcatheter.The device was resheathed with the catheter and removed from the patient¿s body.The device was never deployed or implanted.Product analysis found the returned stent was opened but severely deformed.The as reported codes ¿stent partial deployment¿ and ¿stent failed/unable to open (when not implanted)¿ were not confirmed as the stent was returned and was fully opened.An assignable cause of procedural factors will be assigned to the as analyzed ¿stent deformed¿ as the issue is associated with a product that meets stryker design and manufacture specifications and was used in according with the dfu but due to procedural and/or anatomical factors during use, the product performance was limited.The manufacturer has reviewed all information and determined this event no longer meets the requirement of the reportable event for the device in question.
