(b)(4).The customer returned an opened hemodialysis set including one swg in its advancer, an arrow raulerson syringe (ars), and 18ga introducer needle for evaluation.The guide wire was returned within the advancer tube and showed evidence of use.The guide wire was observed to have no kinks on the body.The distal j-bend was not misshapen and was intact.Both welds were present and were observed to be full and spherical.No other defects or anomalies were observed on the returned components.The overall length of the guide wire measured 603 mm which is within the specification of 596-604 mm per guide wire product drawing.The outer diameter of the guide wire measured 0.850 mm which is within the specifications of 0.838-0.877 mm per guide wire product drawing.The guide wire was advanced through the returned ars and 18ga introducer needle to functionally test the guide wire.The guide wire passed through both components with little to no resistance.Performed per the instructions for use (ifu) statement, "advance guidewire into arrow raulerson syringe approximately 10 cm until it passes through syringe valves or into introducer needle." a manual tug test confirmed that both the distal and proximal welds were intact.A device history record review was performed, and no relevant findings were identified.The ifu provided with the kit describes suggested techniques to minimize the likelihood of guide wire damage during use.The instructions caution, "do not apply excessive force in placing or removing catheter or guidewire.Excessive force can cause component damage or breakage." the report of swg kinked was not able to be confirmed through analysis of the returned sample.There were no kinks or other signs of damage observed on the guide wire.The guide wire met all relevant dimensional and functional requirements, and a device history record review was performed with no relevant findings.Based on these circumstances, no problem was found on the sample.Teleflex will continue to monitor and trend for complaints of this nature.
