Qn#(b)(4) the customer returned one sheath/catheter for analysis.It was observed that a 3-lumen 7fr mac arrow catheter was inserted and locked onto the hub of the mac.Signs of use in the form of biomaterial were observed.Visual analysis of the mac and inserter catheter did not reveal any obvious defects or anomalies.Likewise, analysis down the proximal opening of the hemostasis cap did not reveal any defects with the internal valve.The outer diameter of the distal extension line measured 4.76mm, which is within the specification limits of 4.70mm-4.80mm per the distal extension line extrusion product drawing.The inner diameter of the distal extension line measured 2.997mm, which is within the specification limits of 2.90mm-3.00mm per the distal extension line extrusion product drawing.The outer diameter of the proximal extension line measured 2.90mm, which is within the specification limits of 2.90mm-3.00mm per the proximal extension line extrusion product drawing.The inner diameter of the proximal extension line inner diameter measured 2.159mm, which is within the specification limits of 2.11mm-2.21mm per the proximal extension line extrusion product drawing.The valve and mac device were leak tested according to three different parameters per bs en iso 11070 defined in amrq-000038 rev12.1) low pressure leak resistance test (amrq-000038 section 6.1.2): this states, "using a test pressure of 38-42kpa (5.51-6.09psi), there shall be no leakage past the hemostasis valve".With the inserter cvc catheter removed, the mac was attached to the lab leak tester.With the distal end of the sheath occluded, the sheath was pressurized to 42kpa for 30 seconds.No leaking was observed.2) liquid leakage - hemostasis valve with 7fr catheter inserted: the parameters from the low-pressure leak resistance test were repeated with the returned 7fr catheter inserted into the sheath.The sheath was pressurized with to 42kpa for 30 seconds and no leaks were observed from the hemostasis valve.3) high pressure leak resistance test (amrq-000038 section 6.1.3): this states, "when tested in accordance with iso 11070:,annex d, using a test pressure of 300-320 kpa (43.5 - 46.4 psi) there shall be no leakage sufficient to form a falling drop." with both the distal end of the sheath and the hemostasis valve occluded, the device was pressurized to 300kpa for 30sec.No leaks were detected from any portion of the psi , which indicates that the assembly is intact.No backflow across extension lines or inter lumen crossover was observed during functional testing.The returned 3-lumen cvc was also leak tested.Per amrq-000071 (bs en iso 10555-1 annex c) which states that no liquid leakage should form in one or more falling drops of water when tested at 300kpa for 30 seconds.The extension lines were attached to the leak tester, the distal tip of the catheter was occluded, and the leak tester was turned to 300 kpa for 30 seconds.No leaks were found anywhere on the catheter body or extension line.A manual tug test confirmed that the extension lines were secure within their respective luer hubs.The customer did not provide a lot number; therefore, a device history record review was performed based upon a lot number taken from the sales history data of the customer.No relevant findings were identified.The lidstock product drawing was also reviewed as part of this complaint investigation.It was confirmed that the reported mac catheter is compatible with 7-7.5 fr catheters, which matches the inserted cvc that was returned.The ifu provided with the kit informs the user, "do not suture directly to the outside diameter of access device to minimize the risk of cutting or damaging device or impeding device flow".The customer report of a juncture hub leak could not be confirmed through investigation of the returned sample.The returned mac passed all relevant dimensional and functional requirements including leak testing performed per iso 11070.A device history record review revealed no relevant findings.Based on the customer report and the sample received, no problem was found.Teleflex will continue to monitor and trend on reports of this nature.
