(b)(4).The customer returned one cvc kit with the guide wire assembly for analysis.Signs of use were observed on the guide wire.Visual analysis revealed that the guide wire contained one kink towards the middle of the body.The distal j-bend was intact.Microscopic examination confirmed the kink on the guide wire body and both welds were present and spherical.The kink measured 298mm from the proximal tip of the guide wire.The overall length of the guide wire measured 451mm, which is within the specification limits of 450mm-458mm per the guide wire product drawing.The guide wire outer diameter measured 0.795mm, which is within the specification limits of 0.788mm-0.826mm per the guide wire product drawing.The guide wire was advanced through a lab inventory ars and 18ga introducer needle to functionally test the guide wire.The guide wire passed through both components with minimal resistance.Performed per the instructions-for-use (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 intact.A device history record review was performed, and no relevant findings were identified.The instructions for use (ifu) provided with this kit warns 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 that the guide wire kinked during use was confirmed through examination of the returned sample.The guide wire was observed to have one kink towards the middle of the body.The returned guide wire met all relevant dimensional and functional requirements, and a device history record review did not identify any manufacturing related issues.Based on the condition of the guide wire and the report that the damage was observed during use, unintentional use error caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
