Qn#(b)(4).The customer returned one, unopened hemodialysis kit for analysis.All the kit contents appeared to be present within the tray.Visual analysis revealed a hole/sterility breech on the contour tray.Microscopic examination revealed that the tray around the hole is warped.In addition to this, an unknown, black material was also observed.The appearance of this sterility breach appears consistent with damage as a result of the tray being burned likely during the storage and shipping process.The packaging facility was contacted as part of this complaint investigation.They confirmed that the kit likely came in contact with a heat source, causing the tray to melt.They also indicated that this defect could not have occurred during the packaging process.A device history record review was performed with no relevant findings to suggest a manufacturing related cause.The report of a sterility issue was confirmed through complaint investigation.Visual analysis revealed a hole on the contour tray.Likewise, microscopic examination revealed that the area around the hole was deformed/warped, and a black foreign material was observed.This indicates that the hole was likely caused by an unknown heat source.Based on the customer report and the comments from the packaging facility, the root cause for this complaint is storage and shipping.Teleflex will continue to monitor and trend for report of this nature.
