(b)(4).Catalog# igtcfs-65-jp-jug-tulip.Similar to device under 510(k) (b)(4).(b)(4).Summary of investigational findings: the knob was found bent as reported, but a thorough investigation did not reveal any marks or sign of weakness to the material, which could have caused the incident.Unable to determine reason for the difficulties encountered when attempting to release the filter in the first place and consequently the knob to bend, but excessive tension may have resulted in the deployment difficulties when pressing the release button and consequently pushing it "several times" may have caused the knob to break.Cook medical will continue to monitor for similar events.
