Qn# (b)(4).The customer provided one photo for analysis.The customer also returned an opened cvc kit including one swg in its advancer for evaluation.The guide wire was returned within the advancer tube and showed evidence of use.The guide wire was observed to have multiple kinks towards both the distal and proximal ends of the body.The distal j-bend was misshapen but intact.Microscopic examination confirmed the kinks in the guide wire body.Both welds were present and were observed to be full and spherical.The major kinks in the guide wire were located 11mm, 31mm, 42mm, 429mm, 445mm, and 449mm from the proximal tip.The overall length of the guide wire measured 456 mm which is within the specification of 449.2-458.8 mm per guide wire product drawing.The outer diameter of the guide wire measured 0.512 mm which is within the specifications of 0.508-0.533 mm per guide wire product drawing.The guide wire was advanced through a lab inventory ars and 20ga 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." the report that the guide wire kinked during use was confirmed through examination of the returned sample.The guide wire had multiple kinks towards both the distal and proximal tips.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.
