Age at time of event: 18 years or older.(b)(4).Device evaluated by mfr.: the returned device consisted of a sterling catheter plus an unidentified wire.The balloon was loosely folded and there was blood and contrast in the device.There was damage to the balloon, shaft and tip of the device.The inner shaft and distal markerband were located outside of the balloon (tied/knotted with balloon).Microscopic inspection revealed the distal portion of the balloon was tied in a knot with additional holes visible in the balloon.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The most probable root cause is operational context as device performance was limited due to anatomical/ procedural factors.(b)(4).
