Qn#(b)(4).The customer returned an opened cvc kit including one guide wire within its advancer for evaluation.The guide wire was returned within the advancer tube and no obvious signs of use were observed on the guide wire.The guide wire was observed to have one bend towards the center of the body.The distal j-bend was not misshapen and was intact.Both welds were present and were observed to be full and spherical.No other defects or anomalies were observed on the returned components.The bend in the guide wire measured approximately 200 mm from the proximal tip.The overall length of the guide wire measured 684 mm which is within the specification limits of 678-688 mm per guide wire product drawing.The outer diameter of the guide wire measured 0.851 mm which is within the specification limits of 0.838-0.877 mm per guide wire product drawing.The guide wire was functionally tested per the product instructions-for-use (ifu).The ifu provided with this kit instructs the user, "advance guidewire into arrow raulerson syringe approximately 10 cm until it passes through syringe valves or into introducer needle." the guide wire was advanced through a lab inventory arrow raulerson syringe (ars) and 18ga introducer needle to functionally test the guide wire.The guide wire passed through both components with little to no resistance.A manual tug test confirmed that both 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 the kit describes suggested techniques to minimize the likelihood of guide wire damage during use.The instructions caution , "do not apply excessive force in placing or removing catheter or guidewire.Excessive force can cause component damage or breakage." the report that the guide wire kinked during use was confirmed through examination of the returned sample.The guide wire had one bend towards the center of the body.The returned guide wire met all relevant dimensional/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.
