The device was received for evaluation.During visual inspection, the header cap was removed, and the fibers were noted to be burned.No particulate matter was identified.The reported condition of particulate was not verified; however, the burnt fibers was verified.The cause of the condition of the burnt fibers could not be determined; however, the most probable cause was due to an issue during manufacturing.During the production process hot blades and thermoforming can result in burned fibers.If there is improper or incomplete thermoforming of the fiber bundle can result in a bad cut at hot blade, leading to burned fibers.Production process controls to prevent and detect such defects include 100% visual inspection before a header cap is added to the device.There is another visual inspection when a header cap has been added to the device.A batch review was conducted and there were no deviations found related to this reported condition during the manufacture of this lot.Should additional relevant information become available, a supplemental report will be submitted.
