Received 1 used inlay ureteral stent with the original unit packaging.During the visual evaluation it was observed that the kidney end of the stent was broken.The broken section presented with stress marks as if the stent had been stressed beyond its tensile capabilities.The stent was received out of its individually sealed polybag.The following functional evaluation was performed: take a guidewire of 0.038 in as recommended per instructions for use.Submerged the guidewire and stent in water to activate their coating.Slipped the guidewire through the stent.During the evaluation the stent passed through the guidewire with out any difficulties.A dimensional evaluation was performed: stent length = 10.125 in (specification is 10.24 in ± 0.200 in).Outer diameter = 0.079 in (specification is 0.079 in ± 0.002 in).Inner diameter = 0.050 in (specification is 0.049 in ± 0.002 in).The stent dimensions was found to be within specifications.The device history record was reviewed and found nothing that could have caused or contributed to the reported event.The reported issue was confirmed with an unknown root cause.The instructions for use state the following: " improper handling technique can seriously weaken the stent.Acute bending or overstressing during placement could result in subsequent separation of the stent at the point of stress after a prolonged indwelling period.Exercise care.Tearing of the stent can be caused by sharp instruments.Care should be exercised when removing the stent from inner polybag so as not to cause tearing or fragmentation."
