The following fields were updated due to additional information: d.9.Device available for eval?: yes.D.9.Returned to manufacturer on: 2022-06-20.Investigation: h.6.Investigation summary: twelve photos, three used end caps, and thirty-eight representative samples in open packaging of batch 1356889 were received by our quality team for evaluation.The first photo shows a top web of batch 1356889.Photos 2, 3, and 4 show a used end cap contaminated with blood inside unit packaging.Photo 5 shows a shelf carton label of batch 1356889.Photos 6 and 7 show nine unused end caps with cavity side facing up.Photo 8 shows 9 unused end caps with luer cone tip side facing up.A sink mark is observed on all nine end caps luer cone tip.Photo 9 shows one end cap with cavity 29.Photo 10 and 11 shows one end cap observed with a through hole.Photo 12 shows one end cap in opened packaging.The three used end caps were subjected to visual inspection.The end caps were molded from cavity 29, a sink mark and through hole was observed on the luer cone tip of the returned samples.Of the returned representative samples, two end caps were molded from cavity 16, twelve were molded from cavity 17, nine were molded from cavity 29, two were molded from cavity 30, five were molded from cavity 57, seven were molded from cavity 58, and one was molded from cavity 59.All representative samples were subjected to visual inspection.Nine of the 38 samples failed the visual inspection.A sink mark and through hole was observed on the nine end caps luer cone tip.The nine defective end caps were molded form cavity 29.A review of the internal manufacturing device records and raw material history files for the reported lot number was performed and no recorded quality problems or rejections to this incident were found.The probable root cause for the reported leakage could be due to the sink mark hole at the luer cone tip of the end cap.The air vent may be choked during molding and cause hot air to be trapped.This affects the material flow to the final fill area at the luer cone tip.A project has been initiated to address this issue.This incident has been added to our database of reported incidents.Our business team regularly reviews the collected data for identification of emerging trends.
