Date of event: unknown.The date received by manufacturer has been used.Initial reporter addr: (b)(6).There were multiple lot numbers reported to be involved.The information for each lot number is as follows: medical device lot #: 0266048, medical device expiration date: 2025-08-31, device manufacture date: 2020-09-22.Medical device lot #: 9053732, medical device expiration date: 2024-02-29, device manufacture date: 2019-02-22.Investigation summary: three photos, three representative samples, and seven used samples were received by our quality team for evaluation.From the photo, a defect sample with the cannula pierced through the catheter a defect sample with peelback on the catheter tip was observed.The representative samples were subjected to visual inspection, tip od measurement, bevel angle measurement and penetration testing.All samples passed inspection and no abnormalities were observed.The used samples were subjected to visual inspection, all seven samples were observed with peelback, and one sample was observed with the needle pierced through the catheter.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.There is a 100% online vision inspection for lie distance.If the needle pierced through the catheter during the manufacturing process, the sample will be rejected by the machine.The needle could have pierced through the catheter when the user accidently reinserted the needle back to the catheter during the penetration as the catheter peelback occurred.The probable roto cause for peelback could be due to the tubing material.A trend for the peelback issue has been identified for this product line.The appropriate personnel have been notified of this complaint.We have funded a project to examine how to further increase the robustness of the bd neoflon device and prevent future occurrences of this type.Customer complaint trends will also continue to be evaluated on a monthly basis.Our business team regularly reviews the collected data for identification of emerging trends.Investigation conclusion: 3 returned representative samples pass the visual inspection, tip od measurement, bevel angle measurement and penetration test.All samples passed the acceptance criteria, no abnormality was observed.Needle pierced through catheter was also observed on one of the used sample.There is a 100% online vision inspection for lie distance.If the pierce through happens in the manufacturing process, the sample will be rejected by the machine.The needle pierced through could had happened when user accidentally reinsert the needle back to catheter during penetration as the catheter peelback occurred.Peelback was observed on all the 7 used sample.The probable root cause for peelback could be due to tubing material.Capa# (b)(4) was initiated to address the issue.Complaint trend would be monitored.
