Additional Manufacturer Narrative
The investigation of the returned coil system found the implant to be separated from the pusher with the coils damaged, deformed, and severely stretched at the proximal section.The pusher was not returned for evaluation.The implant's monofilament showed 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.The microcatheter used in the procedure was not evaluated as a part of this evaluation, so the investigation could not determine if it had caused or contributed to the reported complaint.
