(b)(4).Catalog #: igtcfs-65-jp-jug-tulip.Similar to device under 510(k) k090140.Summary of investigational findings: the jugular introducer and sheath are returned.No filter returned.The sheath has two kinks, a smaller one 15 cm proximally and a somewhat larger 30 cm proximally.Apart from the two kinks the sheath appears normal and no sheath perforations.Based on the information provided, it is not possible to conclude an exact root cause for the reported "filter introducer would not advance through the sheath." however, it is possible that the patient anatomy reported caused sheath to kink and that was the reason the introducer would not advance through the sheath.Under normal circumstances the sheath is strong enough to accomplish the procedure, however if excessive force is used to advance the sheath through tortuous anatomy it may kink.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: an ivh catheter was placed in the right jugular vein so the device was introduced via the left jugular vein.The access vessel had moderate tortuosity.After the sheath was advanced to the target site, the filter introducer was inserted into the sheath but it became stuck around the subclavian vein.Upon removal of the delivery system, it was found that the filter was caught on the sheath.Another device was used instead for the procedure.Patient outcome: no adverse effect to the patient.
