H.6.Investigation: one photo received for investigation, one optima injector hub connected to a syringe with the needle exposed was observed.Fifteen retained samples from the same lot were used for additional evaluation.No damage or other defects was observed on any of the product.Functional testing was performed, connecting the injector to a sample syringe, protector and vial according to the instructions for use.Each sample was tested ten times and each time there were no issues observed with the syringes and the injector.Issue observed by the customer (luer lock breakage) could not be replicated on none of retained samples and therefore the event reported could not be confirmed.Moreover, a short-term leakage test was performed on injector for 30 samples, no issues were found that could be involved in the incidence reported.No luer lock breakage nor broken injector safety sleeve was noticed.In all cases, the product functioned properly and there were no issues observed between the connection of the injectors and protector.Product undergoes inspections throughout the manufacturing process to ensure the quality and functionality of the device, including verification all critical dimensions are within specification and there is no damage on the product.A device history review was performed for the reported lot 2101309, no deviations or non-conformances were identified during the manufacturing process that could have contributed to this issue.Testing results were reviewed for the reported lot and found all product met required specifications.Based on the quality team's investigation, we are not able to identify a root cause related to our manufacturing process at this time.H3 other text : see h.10.
