(b)(4).Catalog #: igtcfs-65-2-jug-celect-pt.Similar to device under 510(k) k121629.(b)(4).Summary of investigational findings: no product returned for investigation and without the actual complaint device the exact reason for the difficulties encountered when attempting to release the filter cannot be determined.However, based on information provided "when the delivery system was removed the device was still attached", it is assumed the blue introducer sheath was not withdrawn and the filter was not expanded, when attempts were made to release the filter, ie the filter was still inside the sheath.Ifu: stabilize the introducer, and withdraw the introducer sheath and protection sheath until the protection sheath and handle are connected.At this point the filter is expanded, still connected to the filter introducer.Verify that the sheath hub and handle are connected to ensure that the metal mounting point is completely free of the sheath before filter release.When the filter position is correct, push the red safety button to prepare filter release.Investigation found no evidence to suggest the product was not manufactured according to specifications.Cook medical will continue to monitor for similar events.
