Manufacturer Narrative

B5: additional information received notes the patient is well and at home.The coil with 10 cm of the implant in the vessel was secured without the use of a stent.H:10: a search for non-conformances associated with this part/lot number combination did not reveal any production-related issues relevant to the complaint that occurred during manufacturing of the device.The investigation of the returned coil system found the pusher heater coil damaged, and the implant separated from the pusher.The implant was not returned for evaluation.No indication using a detachment controller was found on the pusher's heater coil.The investigation found the pusher's monofilament with a tensile break shape at the tip which is consistent with the device experiencing excessive force that exceeded the strength of the monofilament causing the implant to separate from the pusher.Further investigation of the pusher found epoxy on the proximal gold connector.The unit passed resistance testing but failed continuity testing.Epoxy present on the gold connector in non-polyimide areas can block the sensor in the v-grip, resulting in the implant coil to not have a consistent connection with the detachment controller during the procedure, which is consistent with the non-detachment described in the reported event.A determination for further investigation has been initiated.This issue will continue to be monitored through the complaint system and tracked by quality.
