Qn#(b)(4).The customer returned the lid stock, introducer needle, and arrow raulerson syringe (ars) from an ak-04301-j kit for evaluation.Visual examination of the syringe and introducer needle did not reveal any defects or anomalies.A vacuum leak test was performed on the syringe per inspection procedure.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 snapped back into a position = 1cc from the starting position.The ars passes the test if the plunger returns to a position = 1cc; therefore, the sample passed the functional inspection.A push leak test was also performed on the syringes per inspection procedure.With the plunger body fully out of the barrel, the tip of the ars was occluded and the plunger was pushed into the barrel.Resistance was felt and the plunger body was not be able to move to the bottom of the syringe, therefore, the sample passed the push leak test.The syringe was used to draw and aspirate water.No issues were identified.The report that the ars leaked could not be confirmed through functional testing of the returned sample.The ars sample passed the vacuum leak test, the push leak tes, and functional testing with water.No leaks were found during testing and the syringe was able to aspirate.The reported complaint issue could not be reproduced with the returned samples.Teleflex will continue to monitor and trend for reports of this nature.
