Qn# (b)(4) the report that the spring wire guide was kinked was confirmed through examination of the returned sample.The customer returned one opened cvc kit, including one guide wire assembly, catheter, and dilator, for evaluation.The end cap and straightener tubing, which are components of the guide wire assembly, were returned but not attached to the assembly.No definite signs of use were observed.Visual analysis revealed that the guide wire contained one kink along the body.Microscopic examination confirmed the damage.The kink on the guide wire would have been protected during packaging, shipping, and storage.Both welds were observed to be full and spherical.No other defects or anomalies were observed with the guide wire, tubing, nor the returned tray.The kink in the guide wire measured 345mm (ruler: ref-003101) form the proximal end.The overall length of the guide wire measured 454mm via calibrated ruler, which was within the specifications of 450-458mm per product drawing.The guide wire outer diameter (od) measured 0.792mm via calibra ted micrometer, which was within the specifications of 0.788-0.826mm per product drawing.The guide wire was functionally tested per the instructions for use (ifu) provided with this kit which instructs the user, " advance guidewire into arrow raulerson syringe ap proximately 10 cm until it passes through syringe valves or into introducer needle".The guide wire was advanced through a lab inventory ars/ 18ga needle subassembly and was able to pass with little to no resistance.The catheter was also advanced over the guide wire, and little to no resistance was experienced.A manual tug test confirmed both welds were intact.A device history record review was performed, and no relevant findings were identified.During normal assembly, the kinked portion of the guidewire are protected within the protective tubing of the advancer assembly, however, the end cap and straightener tube were missing from the assembly.Based on the customer report and sample received, the potential root cannot be determined as it cannot be confirmed when the damage occurred.Teleflex will continue to monitor and trend for complaints of this nature.
