H10: the actual sample was not received for evaluation, however, a picture was provided.Visual inspection observed an image of the header cap area of a dialyzer.On the top of the fiber bundle, were two small dark 'spots', that appeared to be possible singe or burn marks.While the spots looked to be fixed to the bundle top, the actual sample would have to be analyzed for confirmation.The discoloration may be consistent with singe or burn marks caused by debris on the hot blades, the manufacturing equipment used to cut the fiber bundle.Fixed particulate matter, that is not loose in the header cap area, may have potential to enter the dialysate path, however would not be probable to enter the blood path.The reported condition was verified.The cause could not be determined.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.
