Manufacturer Narrative

Implanted date: device was not implanted.Explanted date: device was not explanted.The actual sample was received for evaluation.Visual inspection revealed that the lock adapter had come off the male connector of the sampling system.Magnifying inspection of the actual sample did not find any visible anomaly, including deformity, in the male connector or in the lock adapter.The outer diameter of the rib of the male connector and the inner diameter of the lock adapter were measured.Compared with a current product sample, no difference was observed in the measured values.The surface of the male connector was subjected to elemental analysis by sem-edx (scanning electron microscope / energy dispersive x-ray spectroscopy).The result showed the presence of si, which is likely to be derived from the silicone applied to the switch cocks of the three-way stopcock to improve the lubricity of them in the manufacturing process.Simulation test: silicone was applied to a male connector of a factory-retained sampling system, a female connector was connected to it, and then a lock adapter was tightened up.As a result, the lock adapter came off.Product structure: the sampling system is designed so that the internal step of the lock adapter is hooked on the male connector's ribs to prevent loosening when the female luer is connected.Therefore, if the internal step completely overcomes the ribs for some reason, the mating may come off.Ifu states: do not use if the package or device is damaged (e.G.Cracked) or any of the port caps are off.Based on the provided information and investigation results, there is no definitive evidence that this event was related to a device defect or malfunction.It was likely that the silicon, which is applied to the switch cocks of the sampling system to improve the lubricity, was transferred to the male connector part due to some factors.Afterward, the lock adapter may have come off when re-tightened.However, from the available information including the state of the actual sample, it could not be determined when silicone was transferred to the male connector.The exact cause of the reported event cannot be definitively determined based on the available information.(b)(4).
