Device evaluation: a 37262e product was not available for investigation of pr (b)(4); however, the customer confirmed that the complaint sample was from lot 24109419.The feedback provided by the customer states that, "unable to inject medication into the set." further information from the customer has stated that the complete occlusion was identified during the use of side port in the set by the anesthetists.Moreover, customer has confirmed that the infusate was kept at room temperature prior to infusion and no visible damage on the set before to the use.The details of this feedback were forwarded to the manufacturing site for investigation.A review of the production records for lot 24109419 did not identify any in-process testing failures or quality deviations which may have caused or contributed to a report of this nature.The root cause of the customer¿s experience could not be determined in this instance as no sample was received for investigation.Without a sample to examine it is not possible to determine whether a manufacturing defect could have caused or contributed to a report of this nature.However, previous complaints for occlusions have been related to features on the surface of the male luer of the connecting products.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, without the complaint sample to examine it has not been possible to conclusively link this feedback to a specific failure mode; however, a review of the customer feedback database indicates that this is a rare occurrence with a small number of similar reports against the smartsite component in the past 12 months.
