Additional information is provided in device available for evaluation?, device manufacture date, evaluation codes and additional mfr narrative.No actual sample was received by manufacturing for evaluation.Review of a photo of the complaint device revealed that the luer-lock adapter was detached.No similar complaints are received for this lot.No remarks related to this complaint were reported in the batch record visual inspection.All syringes are visually inspected and items with incompletely assembled luer lock adapters are removed.No loose luer lock adaptors were found for this batch.As no actual sample was returned and no manufacturing related issues were identified, a conclusive root cause could not be determined.As a potential root cause, customer handling could not be eliminated.It is very important that the surgeon properly screws the cannula onto the syringe and that the connection between both devices is checked before using them.Based on the complaint information and the investigation results, we can conclude that the disposition of the product remains unchanged.The complaint could not be verified therefore, no further action is initiated.(b)(4).
