Due to the automated manufacturing execution system (mes) system there are controls in the manufacturing process to ensure the product met specifications upon release.During visual inspection, the subject main coil was seen to be detached.The main coil was seen to be kinked and stretched.The functional inspection was unable to perform as the main coil was returned in the catheter.Apon removal, damage was noted.The reported "coil in catheter friction" and " main coil difficulty inserting "it could not be replicated during device analysis however, the analysis results are consistent with the reported event.The device failed to meet specifications when received for complaint investigation based on the analyzed anomalies noted to the device.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.It was reported that during the procedure, the physician experienced that the subject coil became stuck in the hub of the microcatheter and could not be advanced smoothly.Additional information provided by the customer indicated that the patient¿s anatomy was moderately tortuous.The device was confirmed to be in good condition during preparation and prior to use on the patient, and continuous flushing was established and maintained throughout the clinical procedure.The device was returned for analysis.Upon inspection, the main coil was found detached from the delivery wire and appeared to be excessively stretched and kinked at multiple locations.Functional testing was not performed, as the coil was returned within the catheter, and damage was observed upon removal.Based on the all-available information and analysis of the device it is probable that the subject coil pushed/pulled against resistance may cause the reported and observed defect therefore an assignable cause of 'procedural factors' will be assigned to as reported codes ¿coil in catheter friction¿, ¿main coil difficulty inserting¿ and analyzed codes ¿main coil prematurely detached/separated during use¿, ¿main coil stretched¿, "main coil kinked/bent" as this complaint 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.
