(b)(4).The customer returned one swg in the advancer tubing, a catheter, a dilator, a needle, ars syringe, a catheter-over-needle, a transduction probe, a clamp and a fastener for evaluation.There was no evidence of use on any of the returned components.Visual examination of the returned swg confirmed the guide wire is kinked along its body.The kinked section at the swg assembly thumb guide would not have been protected during shipping, indicating that the guide wire may have been damaged during shipment.The distal j-bend was intact.Both welds appeared spherical and fully formed.The returned guide wire was kinked 520 mm from the proximal tip.The total length of the guide wire measured to be 600 mm which is within specifications of 596-604 mm per product drawing.The outer diameter of the returned guide wire measured to be 0.801 mm which is within specifications of 0.788-0.826 mm per product drawing.The undamaged portions of the returned wire guide passed through the returned 18 ga introducer needle, ars syringe, dilator & distal lumen of the catheter with minimal resistance.Resistance was only encountered at the kinked portion of the swg.A manual tug test confirmed the distal and proximal welds were fully attached.A device history record review was performed with no relevant findings identified.The instructions for use (ifu) provided with the kit (s-15703-112a rev.01) informs the user, "read all package insert warnings, precautions, and instructions prior to use.Failure to do so may result in severe patient injury or death." "do not use if package is damaged." the customer report of guide wire damage before use was confirmed by complaint investigation of the returned sample.The sample passed all relevant dimensional and functional testing, and a device history record review was performed with no relevant findings.The guide wire was returned within its advancer tubing.The tubing showed no kinks or stress marks.The portion of the guide wire that kinked was not protected by the advancer tubing.Based on the condition of the guide wire and the report that the damage was observed before use, storage and shipping caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
