(b)(4).Catalog#: igtcfs-65-2-uni-celect.Similar to device under 510(k) k090140.(b)(4).Summary of investigational findings: femoral and jugular introducer returned.Filter attached to grasping hook of jugular introducer and approx.3mm of primary legs jut out of the protection sheath.The red locking mechanism is pushed.Protection sheath kinked where filter is attached to the introducer, but still filter can easily be advanced and deployed from grasping hook.Based on these findings the exact reason for the deployment difficulties cannot be determined, but it is known from the literature that excessive back tension could result in deployment difficulties/failure when pressing the release button.It is stated in the ifu that: "while keeping slight back tension on the introducer push the release button completely to ensure proper release of the filter.Repositioning of the filter is no longer possible.The filter is now released." and "excessive tension during deployment may prevent the filter from releasing when release mechanism is activated." cook medical will continue to monitor for similar events.
