H3: device eval by manufacturer?: analysis of the returned device was conducted by a bsc quality engineer.The analysis found the inner member condition was not clear due to blood in the system.The distal filter slider (#3) was detached from the device (slider was not bent and had no visible fragments of the inner member).Both filters were returned un-sheathed, and the articulating distal sheath (ads) was not deflected.Testing showed flushing could not be performed through either the distal filter slider (#3) or the rear handle flush port.A test guidewire was fully advanced into the system; the proximal filter sheathed and un-sheathed using the proximal filter slider (#1), and ads articulation was achieved by turning the articulating knob (#2).However, the distal filter could not be sheathed/un-sheathed due to device condition.The reported complaints of handle break and distal filter failure to capture/retrieve were confirmed.Additional testing was performed in order to look further into the issue.The distal filter was able to be sheathed/ and un-sheathed by manually pulling the inner member (supported by a guidewire), and microscopic inspection found the filler tube appeared slightly wavy/buckled on top of the inner member, as well as damaged; no distal filter damage was found.Distal filter slider (#3) was submitted for x-ray inspection and no traces of inner member remains were found inside.Additionally, a.032 inches pin gage was inserted into the detached distal filter slider (#3).
