Manufacturer Narrative

A search for non-conformances associated with the reported 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 returned to the manufacturer for analysis.The investigation is currently ongoing.The instructions for use (ifu) identifies premature coil detachment as a potential complication associated with use of the device.

Event Description

It was reported that an embolization coil implant experienced friction while advancing out of a microcatheter.The coil detached upon retraction.The device was withdrawn from the microcatheter, but a portion of the device was left in the patient.The portion left in the patient was entirely within the treatment site.There was no reported intervention or patient injury.

Manufacturer Narrative

The investigation of the returned coil system found the implant 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 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.
