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 not returned to the manufacturer for evaluation.The alleged product issue could not be confirmed.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 during the embolization treatment of a splenic artery, resistance was encountered between the catheter and the embolization coil and the anatomy was reported to be difficult with many curves.The coil was reported to have detached from the delivery pusher.The coil and microcatheter were removed together as a system.No harm or injury was reported.

Manufacturer Narrative

H10: summary of device evaluation: 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.The pusher was the only component received back for evaluation.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/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.
