Investigation summary: customer returned (8) 1/2cc, 8mm, 30g u40 insulin syringes in an open poly bag from lot # 7142850 and (1) 1/2cc, 8mm, 30g u40 insulin syringes in an open poly bag from lot # 6195894.Customer states that are pouches that have been torn, and from one of the needles a drop of moisture came in when the plunger was pressed.This is lot number 6195894 y (moisture), 7142850 y (torn bags).The poly bag for lot # 7142850 was examined and exhibited an open seal along the back of the poly bag.The syringe returned in the poly bag from lot # 6195894 was examined and no foreign matter was observed in or on the sample.However, a small clear droplet of material came out the cannula when fully depressing the plunger rod.A small portion of this material was removed the sample and prepared for ftir spectral analysis.The spectral analysis shows that this material is most likely silicone.See attached photos and spectra.Silicone is an inert, non-toxic medical substance used as a lubricant for disposable hypodermic products.It is an integral part of the syringe, enabling it to perform as required in various clinical applications and does not present a safety or efficacy issue nor does it impact product function.The silicone application process is designed to provide an even distribution of silicone on the interior of the syringe barrel.When the plunger is fully depressed, the silicone gets distributed along the barrel roof and walls, ensuring a lubricated surface for the plunger to move against.Silicone has been in use in this application for over 20 years, with estimated distribution well in excess of (b)(4) units.No reports are known of adverse clinical effects associated with these products and unintentional delivery of silicone fluid lubricant.Capa # 56537 and situation analysis # bddc-16-871-sa have been opened to address this issue.A review of the device history record was completed for batch# 7142850.All inspections and challenges were performed per the applicable operations qc specifications.There were two (2) notifications [200702334, 200702188] noted that did not pertain to the complaint.A review of the device history record was completed for batch# 6195894.All inspections and challenges were performed per the applicable operations qc specifications.There were zero (0) notifications noted about complaint.Based on the samples / photo(s) received the investigation concluded: confirmed: bd was able to duplicate or confirm the customer¿s indicated failure (excess silicone and open seal).Investigation conclusion: possible root causes for excess silicone include:the first is that some associates do not degas the silicone after refilling the tanks.Second, the silicone volume on the pump is a parameter that is being adjusted, but is not understood and could be a potential kpiv.Capa # (b)(4) and situation analysis # (b)(4) have been opened to address this issue.Possible root cause for the open seal: an inadequate seal was made prior to the bag being cut.This is usually because of a misalignment on the conveyor belt.
