A device history record review was completed for provided material number: 305892 and lot number: 2507006.The review did not reveal any abnormalities detected during the production process that could have contributed to the reported defect, and all quality tests were found to be within specification.To aid in the investigation of this issue, both used and unused samples were received.The samples for lot: 2507006 were also accompanied by a syringe used with a luer lock connection.We have also observed that some of the used needles presented damage in the hub, that might have been done during use.The snap clip (plastic white part inside the hub) was observed not activated, which is crucial to assure a proper connection.The unused needle samples were assembled with the syringe provided and no issues of leakage or failure in connection were noticed.Based on the investigation results, a cause related to the needle manufacturing process could not be determined for this incident.Engagement force is measured prior to the final release of each lot produced and the test results for this lot were found to be within specifications.Smartslip technology ¿ has been introduced to help ensure a secure connection is made with luer slip syringes.It has been designed to reduce the risk of needle disengagement from luer slip syringes (the most common syringe design in europe).We recommend following the instructions for use, which are unique in recommending the user ¿push firmly when attaching the needle to the syringe.¿ and the user should be sure the clip is activated.When attaching the needle to a luer lock connection, a stronger resistance may be felt, this is not preventing a connection from being made.The user should ¿push while twisting¿ however, if the movement is inadvertently paused and the twisting/ turning occurs later, the needle will disengage.At this time, further action has not been determined necessary.Our quality team will continue to closely monitor the manufacturing process for signs of this potential defect and any emerging trends.
