(b)(4).Batch r58x9a.Investigation summary: the analysis results found that the sdh29a device arrived with no apparent damage.The breakaway washer uncut and indented and there were no staples present.Device returned was confirmed to have an uncut washer.Device batch information was reviewed, and it was confirmed to be manufactured within bounding time period of the field action, however based on review of manufacturing records, it was not confirmed to exhibit behavior associated with the field action.The device was reloaded with staples and tested for functionality with a test washer; the device formed all the staples, as well as completely cut the test media and the breakaway washer without incident.The staple line was complete, and the staples meet the staple form release criteria.The condition of the washer indicates that the device had not been fired through a full firing stroke or possibly that the orange indicator was not fully into the safe green firing range.It should be noted that before firing the device the orange indicator should be fully within the green range of the gap setting scale.In addition, it should be noted that if the firing sequence is not complete (the firing handle reaches its stopping point, and the firing trigger is parallel to the instrument handle) staples could be partially deployed without cutting the washer.Please reference the instructions for use for additional information.A manufacturing record evaluation was performed for the finished device batch number, and no non-conformances were identified.
