(b)(4).Catalog #: igtcfs-65-2-uni-celect.Similar to device under 510(k) k090140.Summary of investigational findings: investigation is based on event description and returned product.Filter and long dilator returned together with femoral introducer and jugular introducer system inside ripped sheath; ~5cm of the blue sheath is still attached to the handle portion and ~35cm of the distal end of sheath is covering distal end of jugular introducer - in between the two sheath portions ~20cm sheath is missing.These findings do not match the report stating that filter came out of sheath after femoral approach.Femoral introducer slightly bent, but working as intended.Red safety button unlocked.Remains of blood on piston/cup and on the tactile bump.Jugular introducer apparently used, but red safety button is still locked.Remains of blood on grasping hook and protection sheath is damaged at the tip, probably by filter anchoring hooks.Furthermore, 5 cm sheath still attached to handle is penetrated/ripped ~3cm from handle - probably by primary filter legs (also indicating jugular approach).Primary filter legs are symmetric, but one secondary leg is out of shape and two others are not symmetric.Under normal conditions the sheath is strong enough to accomplish the procedure, and based on investigation findings and information provided the exact reason for filter to penetrate the sheath cannot be determined and also not for the missing sheath portion.From the ifu: ¿filter placement: excessive force should not be used to place filter.¿ there is found no evidence to suggest that this device was not manufactured according to specifications.Cook medical will continue to monitor for similar events.
