Manufacturer Narrative

Due to the automated manufacturing execution system (mes) there are controls in the manufacturing process to ensure the product met specifications upon release.During visual/microscopic inspection, the coil delivery wire was noted to be kinked/bent.The main coil was noted to be stretched.The introducer sheath and catheter were not returned.Functional testing was unable to perform due to damage.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 could not be confirmed, and it could not be definitively determined if the device failed to meet specifications as the catheter was not returned along with the introducer sheath.Additional information provided by the customer indicated that no damage was noted to the packaging prior to opening the packaging.The device was prepared for use as per the directions for use.Continues flush was maintained throughout the procedure.Resistance was encountered in the microcatheter.The coil was withdrawn and found thrombus generated in microcatheter.An assignable cause of procedural factors will be assigned to the as reported 'coil in catheter friction' as these defects appears to be associated with a product that met stryker design and manufacturing specifications and was used in accordance with the dfu, but performance was limited due to procedural factors during use.Based upon medical review, the harm observed in this complaint is anticipated in nature as per the device risk assessment.The reported 'patient vessel thrombosis is a known and anticipated complication to these types of procedures and patient condition and is listed as such in the device directions for use.Therefore, a probable cause of anticipated procedural complication was assigned to this event.An assignable cause of procedural factors will be assigned to the as analyzed 'coil delivery wire kinked/bent' and 'main coil stretched' as these defects appears to be associated with a product that met stryker design and manufacturing specifications and was used in accordance with the dfu, but performance was limited due to procedural factors during use.
