Exemption number e2016032.(b)(4).Manufacturers ref# (b)(4).(b)(4).Summary of investigational findings: investigation is based on event description and returned device.The complete device was returned in original tray, but with separated filter.Three pair of secondary legs were crossed.The handle of the introducer was slightly bent, but despite remnants of blood on the piston and the cup, the femoral introducer worked as intended and no damages were noted.Based on very limited information provided it cannot be determined if the filter would not release or if it would not expand.However, it is assumed that the filter would not release from the femoral introducer, but based on the findings the exact reason for this to occur cannot be determined.No evidence to suggest that this device was not manufactured according to specifications and nothing indicates that it did not perform as intended.Cook medical will continue to monitor for similar events.
