Investigation summary: three 2000e (b)(4) samples were received for investigation, two in opened packaging from lot 21045802 and one was received without packaging.No connecting products were received t assist the investigation in this instance.Functional testing was performed by connecting a bd plastipak 50ml syringe to the received samples.It was observed for all three samples, the piston of the smartsite opened and no occlusion was observed.The details of this feedback were forwarded to the manufacturing site for investigation.A review of the production records for lot 21045802 did not identify any in-process testing failures or quality deviations which may have resulted in a report of this nature.In this instance, a definitive root cause could not be identified as testing of the returned samples did not identify any product defects that could have contributed to the customer¿s experience.However following a small number of similar reports, bd has conducted an in-depth investigation to identify any potential contributing factors for occlusion of this nature.The investigation has determined that a potential contributor could be the result of an insufficient amount of fluorosilicone having been injected into the piston of the smartsite during the assembly process; fluorosilicone is used as a lubricant within the smartsite to ensure the consistent opening of the piston when the smartsite is activated, and an insufficient amount may cause a temporary occlusion.Please note previous investigations have also determined that features on the surface of the male luer of the connecting products may also contribute to the reported occlusion.These features include flash or a raised edge to the tip of the male luer which have previously been shown to intermittently lead to restricted flow due to them pinching the blue piston of the smartsite and not allowing it to open.This can sometimes be resolved by disconnecting and reattaching the same luer connection which may reposition the luer against the piston and improve the flow, or alternatively by changing the connecting male luer.In this instance as the reported occlusion was not replicated during testing of the returned samples, and the connecting products were not returned as part of the investigation it could not be determined which is the most likely root cause for the customer's experience in this instance.Please note, in order to minimize reports for occlusions of this nature, the manufacturing site has repaired the assembly machine to ensure that an adequate amount of fluorosilicone is injected into each smartsite.A review of the customer feedback database indicates that this is a rare occurrence with a small number of similar reports against the 2000e (b)(4) set in the past 12 months.
