Manufacturer Narrative

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 device was stated to be available for return to the manufacturer for evaluation but has not yet been returned.The alleged product issue could not be confirmed.If the device is received at a later date, an investigation will be performed and a supplemental mdr will be submitted.The instructions for use (ifu) identifies premature coil detachment as a potential complication associated with the use of the device.

Event Description

It was reported that during an embolization procedure of a recanalized a-com aneurysm.A coil could not be detached after multiple attempts with two detachment controllers.The doctor decided to remove the coil from the patient and found that the coil had stretched and broke off.Part of the coil was placed in the aneurysm and part in the parent artery.An atlas stent was used to secure the coil wire and the aneurysm was closed.There was no reported patient injury.

Manufacturer Narrative

Investigation conclusion: the investigation of the returned coil system found the pusher heater coil stretched, broken and entangled at the middle section, the yellow lead wire broken, and the implant not attached to the pusher with indications of activation observed on the pusher heater coil; however, the pusher'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.As the lead wire was returned broken, this investigation could not test or assess the continuity or resistance of the pusher to determine if a condition existed that would have caused or contributed to the alleged non-detachment issue.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.
