The device history record review confirms that the device met all material, assembly and performance specifications.The subject device was returned with the microcatheter used during the procedure.Visual inspection of the device revealed that the main coil was returned un- attached and broken from the delivery wire at the main coil junction.The main coil was found to be kinked towards the proximal end as well.No other anomalies were observed.Functional testing could not be performed due to the damaged condition of the returned coil.A patency test was performed on the returned microcatheter and no resistance was noted.Information available indicated that the device was confirmed to be in good condition prior to use and was prepared as per the dfu.It is likely that the main coil was damaged during use thus limiting the performance of the coil during the clinical procedure.Therefore, an assignable cause of operational context has been assigned to this investigation.
