Exemption number e2016032.(b)(4).Name and address for importer site: (b)(4).Summary of investigational findings: investigation is based on event description and returned product.Only the femoral introducer with loaded filter was returned.One of the secondary filter legs was wrinkled and another was squeezed under a third secondary leg.The filter hook was straightened.On the femoral introducer the locking mechanism was not pressed, ie the system was still locked, but after unlocking it worked as intended and the filter released without difficulty.The locked system may have been the reason for the filter to "not release upon deployment" and probably retrieving the filter through the sheath and the valve may have damaged the filter and misplaced the filter legs.The reason for the straightened filter hook cannot be determined, unless a loop device was placed via jugular approach and attempts were made to release the filter by pulling it from there.It is noted that the patient experienced no adverse effects and that another filter was placed.Ifu: when the filter position is correct, push the red safety button to prepare filter release.No evidence to suggest that this device was not manufactured according to specifications.Cook medical will continue to monitor for similar events.
