Device evaluated by mfr: a visual examination of the returned device found that the stent was partially deployed by 1mm and that the distal stent wires were kinked.The outer sheath was probably pushed proximally exposing the stent wires during the attempt to cross the lesion.Dried blood was noted along the shaft and no issues were noted with the profile of the delivery device.Measurement of the od of the device at various locations found that all measurements were within the system profile specification.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).
