Event or Problem Description
It was reported that the physician was performing an ovarian vein embolization and when an embolization coil implant was being removed from its packaging, it was noticed that the delivery pusher was already kinked.The pusher was straightened and used.The implant detached from the delivery pusher in the microcatheter.There was no reported pateint injury or intervention.
Additional Manufacturer Narrative
The investigation of the returned coil system found the implant stretched at proximal and to be 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 stretched tail/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.
