Upon removal of the angiographic vessel dilator from the catheter sheath introducer of an argon option elite inferior vena cava filter system, it was noted that one of the two radiopaque markers on the distal aspect of the dilator had come free off the dilator and was lodged at the distal end of the catheter sheath introducer.The dilator was then carefully removed from the sheath under fluoroscopic guidance and multiple attempts were then made with a snare device to grasp the marker, which were unsuccessful.Multiple attempts were then made to pass an 0.018 microwire through the marker and use an angioplasty balloon to capture the marker, which were also unsuccessful.At this point, due to the manipulation, the marker embolized into a small branch of the right internal iliac vein.The right internal jugular vein was then accessed and similar attempts were made to capture the marker from this approach, which were unsuccessful.Another argon option elite inferior vena cava filter system was opened and the filter was successfully deployed from the internal jugular approach.All components of the first set were sent to the manufacturer for analysis.Fda safety report id# (b)(4).
