Product complaint#: (b)(4).A supplemental report will be submitted if new facts arise which materially alter information submitted in a previous mdr report.Complaint conclusion: as reported by the field, during a coil embolization, a 5mmx17cm presidio 10 cere coil (pc410051730, s14481) couldn¿t be detached.The physician withdrew the problem coil outside of patient and changed to another new coil to complete the procedure.There was no patient injury reported.No additional information is available.One non-sterile presidio 10 cere 5mmx17cm unit was received inside of a pouch.The received device was visually inspected, and the core wire was found damaged, biological material could me observed inside the device and in contact with the dpu.Then a microscopic inspection was performed, and the distal outer sheath had not been softened indicating that the resistance heating coil had not been heated and the detachment process was not initiated.No other damages were observed.The resistance of the device was measured with multimeter and a lab sample enpower control cable.Resistance initially measured approximately 35.3 o, which is out of the specification range.Also, the device was connected to detachment control box dcb00000500 (dcb) with a enpower control cable lab sample and the power was turned on.The system ready light was not illuminating.Due to these conditions the detach cycle could not be performed.A manufacturing record evaluation was performed for the finished device s14481 number, and no non-conformances related to the reported complaint condition were identified.The complaint reported by the customer ¿coil - failure to detach¿ was confirmed as the detachment cycle could not be performed due to the the resistances of the device was found out of the specification range.The core wire was found damaged, this could have been caused by an external force, the same force may have damaged the core wire of the device contributing to the lack of resistance values on the multimeter.Residues of biological material and saline solution could also be observed inside the outer sheath and in contact with the dpu wires, which it seems to be entered into the device from the distal section of the dpu which may contribute as well to the device failure.Neither the analysis nor the mre suggest that the failure reported could be related to the manufacturing process.Failure to detach is a known potential issue associated with the use of this device.The instructions for use (ifu) contains several precautions related to this issue and includes instructions for troubleshooting the situation should it be encountered during use.Assignment of root cause for the event remains speculative and inconclusive, based on the limited information provided and the evidence presented by the returned device; however, it is possible that clinical and procedural factors, including device manipulation and device interaction, may have contributed to the reported failure and damages on the returned system.As part of the post market surveillance program, information from this complaint is trended to identify statistical signals for consideration of further correction action.Since there was no evidence to suggest the event was related to a manufacturing or design issue, no corrective actions will be taken at this time.
