(b)(4).Device evaluation: the report that the arrow raulerson syringe (ars) was found leaking when attempting to aspirate from the vein was not confirmed.Returned was one raulerson syringe/introducer needle assembly.The ars syringe appeared typical.The luer taper at the tip of the syringe was found to be acceptable.A vacuum leak test was performed on the ars.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 and it returned to its original position, which passed the test.The needle appeared typical.The luer taper of the hub passed luer gage testing.The needle attached firmly to the ars syringe.Water was aspirated into the assembly five times with no air bubbles or signs of a leak.A review of the device history records for the ars / needle assembly did not reveal any manufacturing related issues.The ars passed vacuum testing and the ars/needle assembly did not leak during functional aspiration testing.No problem was found on the sample.No further action will be taken.
