(b)(4).Catalog#: igtcfs-65-1-fem-celect-pt.(b)(4).Summary of investigational findings: only a venogram was provided and demonstrated 19° of leftward tilt and the proximal 10 mm of filter projected outside of column of contrast, meeting the definition of penetration.In addition, primary and secondary legs along the right appeared cranially displaced resulting in tenting of the right lateral ivc wall.The venogram did not explain the reason why "the filter deployed sideways and none of the legs opened", but the sheath may have been advanced either through the ivc wall or into a collateral vein.Potentially, the filter was deployed in extracaval location, as that would inhibit the filter legs from opening normally.After deployment a snare was utilized to pull the filter caudally, at which point the legs expanded into the ivc and consequently appeared cranially displaced.It is noted that the filter placement had no adverse effects on the patient.No evidence to suggest that this device was not manufactured according to specifications and nothing indicates that the filter did not perform as intended, e.G.Intended for the prevention of recurrent pulmonary embolism (pe) via placement in the vena cava.Cook medical will continue to monitor for similar events.
