(b)(4).The customer returned one, opened cvc kit for analysis.No obvious signs of use were observed.The guide wire was removed from the tubing, and no obvious kinks or bends were observed.Microscopic examination confirmed that the j-bend is intact, and the distal and proximal welds are full and spherical.No other defects or anomalies were observed on the guide wire nor the tubing.The guide wire length measured 602mm, which is within the specification limits of 596mm-604mm per the guide wire product drawing.The guide wire outer diameter measured 0.800mm, which is within the specification limits of 0.788mm-0.826mm per the guide wire product drawing.The guide wire was passed through the returned ars/introducer needle subassembly.No resistance was encountered as the guide wire passed completely through the subassembly.Performed per 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 the distal and proximal welds are secure and intact.A device history record review was performed, and no relevant findings were identified.The ifu provided with the kit informs the user, "do not use excessive force when introducing guidewire or tissue dilator as this can lead to vessel perforation, bleeding, or component damage".The report of a kinked guide wire could not be confirmed through analysis of the returned sample.Visual analysis did not reveal any kinks/bends on the guide wire.Likewise, the sample met all relevant dimensional and functional requirements, and a device history record review did not reveal any relevant findings.Based on the customer report and the sample received, no problem was found with the returned device.Teleflex will continue to monitor and trend for reports of this nature.
