A heli-fx applier and endoanchors were used in the endovascular treatment of the patient for a type ia endoleak.The patient had an endurant stent graft system implanted on the same date.It was reported that during the index procedure, after observation of a type ia endoleak, the physician tried to operate the heli-fx applier but it malfunctioned and would only work intermittently for loading from the cassette and deployment of the endoanchor into the stent graft.The physician managed to load and implant 3 endoanchors but the remaining time the heli-fx applier wouldn't retract and the endoanchors couldn't be loaded from the cassette.It was noted that as the endoanchor could not be released fully from the heli-fx applier after deployment, the stent graft was pulled back during removal of the applier, leading to infolding of the stent graft.It is unknown whether the difficulty removing the applier after endoanchor deployment was noted before malfunctioning of the device.It was reported that only gentle force was used to pull back the stuck heli-fx applier.As per the physician, the cause of the event is due to malfunction of the applier and the cause of the type ia endoleak was due to complex anatomy of the proximal neck.The type ia endoleak was unresolved.No additional clinical sequelae were reported and the patient will be monitored.
