Additional Manufacturer Narrative
Additional information: h3, h6, h10 (summary device evaluation).Summary of device evaluation: the reported complaint is confirmed.The investigation of the returned coil system found the implant stretched and separated from the pusher.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.The physical evaluation of the device could not identify the conditions or circumstances that led to the damage, but the damage is consistent with the device experiencing forces over specification.
