The concerned device "jackal rx" is a rapid-exchange (rx) type semi-compliant pta balloon dilatation catheter compatible to 0.018" guidewire (gw)."jackal rx" has no approval in the us, however, we will report this case as an incident occurred on a similar device for "crosstella rx" (a rx-type pta balloon dilatation catheter, compatible to 0.018" gw) that is distributed in the us under 510(k) # k152873.The actual device concerned was returned and investigated.In the actual product, the fracture surface was a straight vertical balloon crack at about 30 to 38 mm from the tip, and the fracture surface was wavy circumferential tear at the 38 mm part.The device history records (dhr) of the device concerned was reviewed: the production lot, to which the device concerned belongs, passed all in-process inspections including the shaft-pressurized test and the balloon-wrapping test for every product, and the finished product inspections including the shaft tensile strength test and the repetitive balloon inflation/deflation test on representative samples based on sampling plan.No nonconformity or abnormality in the manufacturing processes of the device concerned was found.Probable cause(s) and our comment: the procedure information suggested that there was a possibility of being caught and ruptured by gc at the time of removal after rupture.No nonconformity or abnormality in the manufacturing processes of the device concerned was found, and accordingly, we determine that the event reported was caused by not any defect of the device but the user's handling issues.
