Qn#(b)(4) the customer provided one image showing multiple guide wire assemblies.Kinking on at least one guide wire is visible.The customer also returned one guide wire assembly for analysis.The straightener tubing and cap were not included.Signs of use in the form of biological material were observed on the guide wire surface.Visual analysis revealed one kink towards the distal end.Microscopic examination confirmed the damage and revealed that the distal and proximal welds were full and spherical.No obvious defects were noted with the j-bend nor the guide wire tubing.After failing dimensional analysis, the returned sample was compared with the guide wire product drawing.The markings on the returned sample do not match the markings on the product drawing.The kink on the guide wire measured from the proximal weld.The guide wire total length measured 685mm, which is not within the specification limits of 596mm-604mm per the guide wire product drawing.The guide wire outer diameter measured 0.830mm, which is not within the specification limits of 0.788mm-0.826mm per the guide wire product drawing.The discrepancy with the guide wire length and outer diameter measuring out of specification indicates that either the incorrect guide wire was returned , or the incorrect finished good was reported.The returned guide wire was inserted through a lab inventory arrow raulerson syringe (ars)/introducer needle subassembly.Little to no resistance was encountered as the guide wire passed completely through the assembly.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 were 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 apply excessive force in placing or removing catheter or guidewire.Excessive force can cause component damage or breakage.If damage is suspected or withdrawal cannot be easily accomplished, radiographic visualization should be obtained and further consultation requested".The report of a kinked guide wire was confirmed through complaint investigation of the returned sample.The guide wire was kinked towards the distal end; however, the guide wire length and outer diameter did not meet the specification requirements.It is unknown if the incorrect guide wire was returned or if the incorrect finished good was reported.A device history record review was performed on the reported finished good with no relevant findings.Based on the customer report and the kinking observed on the returned sample, the failure appears consistent with damage due to unintentional use error; however, due to the dimensional discrepancies and the fact that the guide wire markings do not match what is shown in the product drawing , the root cause cannot be determined.Teleflex will continue to monitor and trend for reports of this nature.
