(b)(4).The customer returned one ars and introducer needle for investigation.After the ars failed functional testing, the valves were removed from the ars and microscopically examined.One of the valves was observed to have a hole in the center of the valve.The returned sample was functionally tested in accordance with the instructions-for-use (ifu) provided with this kit.The ifu instructs the user, "insert introducer needle or catheter/needle with attached syringe or arrow raulerson syringe (where provided) into vein and aspirate." the syringe was not able to draw and aspirate water with a lab inventory introducer needle attached.Mainly air was drawn into the syringe body as the plunger was pulled back.The module requirement document for raulerson syringes (amrq-000113 rev.04) was reviewed to determine requirements for air/water leakage.The document notes a deviation from iso 7886-1: "the freedom of air and liquid leakage past the piston requirement is design restrictive and is intended for an injection-intended syringe, not the ars.The opening in the center of the piston that allows passage of the inner cannula prohibits the ars from meeting the pressure and vacuum requirements as dictated by the standard.However, because the intended use of the ars is to allow aspiration of blood to ensure venous placement of the introducer needle and to aid in the insertion of the spring wire guide, the leakage requirements of a standard syringe are not applicable to the ars." a vacuum test was performed on the ars syringe in order to verify that the internal valves within the plunger body was intact.With the plunger body at the bottom of the syringe, the tip of the ars was occluded, and the plunger was pulled back until it stopped.With the tip of the ars still occluded, the plunger was released but did not snap back into the starting position.Therefore, the internal valves of the ars are not functioning as intended.A device history record review was performed and no relevant findings were identified.The ifu provided with this kit instructs the user, "insert introducer needle or catheter/needle with attached syringe or arrow raulerson syringe (where provided) into vein and aspirate." the issue of the ars leaking was confirmed during functional testing of the returned sample.The returned syringe failed the vacuum test.Further examination of the valves revealed small puncture holes in both of the valves.A device history record review was performed and did not reveal any relevant findings.A capa has been initiated to further investigate this complaint issue; corrective actions have not yet been implemented.Teleflex will continue to monitor and trend reports of this nature.
