Qn# (b)(4).The customer provided one photo for analysis.The complaint of swg kinked was able to be confirmed by the photo.The customer also returned an opened cvc kit including one swg in its advancer, an arrow raulerson syringe (ars), and an 18ga introducer needle for evaluation.The guide wire was returned within the advancer tube.No obvious signs of use was observed.The guide wire was observed to have a one kink on the distal j-bend of the body.The distal j-bend was not misshapen and was intact.Microscopic examination confirmed the kink in the guide wire body.Both welds were present and were observed to be full and spherical.The kink in the guide wire was located 3 mm from the distal tip.The overall length of the guide wire measured 602 mm which is within the specification of 596-604 mm per guide wire product drawing.The outer diameter of the guide wire measured 0.805 mm which is within the specification of 0.788-0.826 mm per guide wire product drawing.The guide wire was advanced through the returned ars and 18ga introducer needle to functionally test the guide wire.The guide wire passed through both components with little to no 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 both the distal and proximal welds were intact.A device history record review was performed, and no relevant findings were identified.The 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.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 had one kink on the distal j-bend.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.
