(b)(4).Catalog #: igtcfs-65-jp-jug-tulip.Similar to device under 510(k) k090140.(b)(4).Summary of investigational findings: two sheaths were received for investigation.The two sheaths were used for one patient.Sheath no.1 has a severe kink and penetration appears approximately 25 cm from distal end.Sheath no.2 has a severe penetration appears approximately 25 cm from distal end.Under normal conditions the sheath is strong enough to accomplish the procedure, but it has been seen before that the sheath may kink if somehow exposed to excessive force because of tortuous anatomy.If the filter is advanced through a kinked/severely curved sheath, the filter legs may be prone to exceed the sheath wall.No evidence to suggest that this device was not manufactured according to specifications.Cook medical will continue to monitor for similar events.

Description of event according to initial reporter: the device was inserted from the left jugular vein.After checking bloodstream, the filter introducer was advanced into the sheath carefully.However, it made the sheath kinked (lot e2998011 or e3014754).Then, another same device was used instead, but the same event occurred (lot e2998011 or e3014754).Since vessel (vein) damage was confirmed, the procedure was finished.Additional information received 22mar2013: the reason why the approaching point was from left was that hematoma occurred in the access route of the right jugular vein.Dissection was confirmed but the physician decided to take a wait-and-see approach.Patient outcome: there has been no patient outcome reported.
