Udi - the corresponding lot is not subjected for udi; implanted date: device was not implanted; explanted date: device was not explanted; device manufacture date - 11/04/18 ~ 11/07/2018.Initial reporter: (b)(6).(b)(4).The actual device and one unused sample was returned to the manufacturing facility for evaluation.The actual sample was observed visually, a part of the catheter was snapped off approximately 9mm away from its root.Since the snapped catheter alone is measured approximately 22mm long, no missing portion is expected.When closely checked the damaged portion under microscopic observation, the damage was appeared to be squeezed while the damage surface was in both smooth and rough portion.The unused sample was then visually observed.No irregularity that could have attributed physical deformation or scratch on catheter, were observed.The manufacture inspection record was traced back and reviewed.No defective properties catheter snap or scratch to degrade functionally of the catheter were detected.Furthermore, there has been no similar event ever reported by other medical institutions.The reported damage seen on the catheter is presumed to be done by unintentional contact with a sharp object.The damage on the catheter might have been to be stretched afterward and separated as consequence.(b)(4).
