Event Description
|
Medtronic received information reporting that a coil was stretched and the wire was cut and left in the patient's body.That patient was undergoing a coil embolization procedure to treat a saccular c6 segment aneurysm.The aneurysm max diameter was 7mm and the neck diameter was 5mm.Vessel tortuosity was normal.It was reported that during the procedure, the qc-7-30-helix coil was second coil to be used.There was no friction or other difficulty observed during testing or delivery of the coil.The surgeon performed several adjustments such as pushing and pulling the coil after which the coil was stretched but not detached.The surgeon withdrew the spring wire and the catheter together but the distal end of the coil remained connected with the coil implanted in the aneurysm and could not be withdrawn completely from the patient's body.At the femoral artery access, the surgeon cut the stretched spring wire shore and part of the wire stayed in the patient's body.It was noted the length of the spring wire in the body extended approximately from the aneurysm to the femoral artery puncture site.Subsequently, the surgeon implanted a solitaire stent to prevent the wire from floating excessively in the patient's vessel.It was unknown if the patient experienced any symptoms or additional complications associated with the event at the time the report was received.
