(b)(4).The customer returned one guide wire assembly and arrow raulerson syringe (ars) 18ga introducer needle for analysis.The guide wire was returned assembled within the tubing.Signs of use in the form of biological material were observed.Visual analysis revealed that the guide wire was kinked towards the distal end.The j-bend was also observed to be misshapen.Microscopic examination confirmed the damage and revealed that the distal and proximal welds were secure and intact.No defects or anomalies were noted with the ars nor the introducer needle.The kink on the guide wire measured 415mm from the proximal weld.The guide wire length measured 457mm, which is within the specification limits of 450mm-458mm per the guide wire product drawing.The guide wire outer diameter measured 0.790mm, which is within the specification limits of 0.788mm-0.826mm per the guide wire product drawing.The returned guide wire was inserted through the ars/introducer needle subassembly.Little to 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 were secure and intact.A device history record reviews was performed with no relevant findings.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.Visual analysis revealed that the guide wire was kinked towards the distal end.Despite the damage, 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, unintentional use error likely caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
