(b)(4).The customer returned one, opened cvc kit for analysis.The guide wire, arrow raulerson syringe (ars) , and introducer needle will be analyzed as part of this complaint investigation.The sample was returned with the guide wire partially advanced through the ars/introducer needle subassembly.Signs of use were observed inside the ars.Visual analysis revealed that the guide wire was kinked in an area that was located inside the ars.The guide wire was completely removed, and the distal j-bend was observed to be misshapen.Microscopic examination confirmed the damage and revealed that the distal and proximal welds were secure and intact.The kink on the guide wire measured 516mm from the distal weld.The guide wire length measured 603mm, which is within the specification limits of 596mm-604mm per the guide wire product drawing.The guide wire outer diameter measured 0.79mm, which is within the specification limits of 0.788mm-0.826mm per the guide wire product drawing.The guide wire was removed and reinserted back through the ars/introducer needle subassembly.Minor resistance was observed at the location of the kinking; however, all functional portions of the guide wire were able to pass with little to no resistance.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.Visual analysis revealed a kink around the middle of the guide wire.This kink created minor resistance when being inserted through the ars/introducer needle subassembly.Despite the damage, the guide wire met all relevant dimensional 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.
