Qn# (b)(4).The customer report of a kinked guide wire could not be confirmed through complaint investigation of the returned sample.The customer returned one opened cvc set with multiple components, including a guide wire, for analysis.The guide wire was returned within its advancer tube and showed evidence of use.Visual inspection of the guide wire revealed no obvious defects or anomalies.No visible kinks were observed on the guide wire.The distal j-bend was present and appeared intact.Both welds were present and appeared full and spherical.The guide wire total length measured 456mm via calibrated ruler, which was within the specifications of 450-458mm per product drawing.The guide wire outer diameter (od) measured 0.79mm via calibrated caliper, which was within the specifications of 0.788-0.826mm per product drawing.Functional inspection of the guide wire was performed per the instructions-for-use (ifu) provided with the kit which states, "advance guidewire into arrow raulerson syringe approximately 10 cm until it passes through syringe valves or into introducer needle." the guide wire was able to pass through the returned arrow raulerson syringe (ars) and a lab inventory introducer needle with no resistance.A manual tug test confirmed the distal and proximal welds were intact.The instructions-for-use (ifu) provided with the kit describes suggested techniques to minimize the likelihood of guide wire damage during use.The instructions caution that withdrawing the guide wire against the needle bevel or use of excessive force during removal could damage or break the wire.A device history record review was performed on the guide wire and no relevant manufacturing issues were identified.Based on these circumstances, no problem was found with the returned sample.Teleflex will continue to monitor and trend for complaints of this nature.
