Due to the automated manufacturing execution system (mes) there are controls in the manufacturing process to ensure the product met specifications upon release.During the visual inspection-the catheter shaft was kinked.The catheter shaft was flattened.The catheter tip was intact.The catheter hub was intact.During functional inspection- the catheter was flushed and a patency mandrel was advanced through the microcatheter, the patency mandrel would not advance from the hub.The catheter shaft was cut and ptfe inner lining was removed from the catheter shaft.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 confirmed based on analysis.The device failed to meet specification when received for complaint investigation based on the analyzed anomalies noted to the device.The product was returned, and the as analyzed codes listed in the below product problem code(s) grid were found.Additional information provided by the customer indicated that there was no damage noted to the packaging prior to opening and the device was confirmed to be in good condition during preparation/prior to use on the patient.Also additional information received indicated that the device was being used in a severe stenosis case and the upper segment was occluded completely which could have contributed to the event.The damage noted to the device would be indicative of the as reported defect.It was seen that the microcatheter was flattened and kinked and the patency mandrel could not be advanced during analysis.The catheter shaft was blocked and ptfe lining was removed from the catheter shaft.The ptfe lining most likely peeled due to the friction trying to advance the stent during the procedure and the patency mandrel during analysis.The microcatheter most likely was damaged during the procedure due to some procedural/anatomical factors encountered during use leading to the reported and analyzed defects.Based on the investigation results and available information, an assignable cause of procedural factors will be assigned to the as reported.
