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.However, procedural imaging was provided.The investigation is ongoing.Upon completion of the investigation, a supplemental mdr will be submitted.

Event Description

It was reported that after the sofia was inserted using a glidesheath and microcatheter, onyx was injected.Immediately after injection, the physician then noticed the distal end of the sofia appeared to be unwinding.The entire system was removed.After removal, the catheter¿s internal coiling was hanging out at the end.The procedure was completed.There was no adverse impact to the patient.

Manufacturer Narrative

Two radiographic images were provided for review.Image 1 is a left ica ap oblique roadmap.It shows the ica at the skull base all the way to the ica terminus and bifurcation.A catheter (presumably the sofia described in the complaint) is positioned at the proximal petrous segment.Pulsation motion artifact is seen at the tip of the catheter.Image 2 is a roadmap taken during onyx or contrast injection into an avm.Part of the nidus contains onyx which was injected prior to the roadmap and is subtracted out.Either onyx or contrast is being injected into the nidus of the avm via a microcatheter.The tip of the sofia is still in the proximal petrous segment.The cause of the problem described with the tip of the sofia is not seen on these images.However, the investigation of the returned sofia catheter found a coil dislodged from the interior of the catheter at approximately 11-12cm from the distal end, and the dislodged coil was found protruding from the distal tip, which is consistent with the alleged product issue.The physical evaluation of the device could not identify the conditions or circumstances that led to the dislodged coil, but the damage is consistent with the device experiencing forces over specification.
