(b)(4).Device evaluated by mfr: returned product consisted of a coyote balloon catheter with a stopcock attached to the hub.The balloon was loosely folded with blood in the hub, balloon, inflation lumen and wire lumen.The device was soaked in a warm waterbath for 5 days.The tip, balloon, markerband, inner/outer shaft (lumen) were microscopically, tactile and visually inspected.Inspection revealed a pinhole in the balloon material located 11.5cm proximally from the distal markerband.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.The investigation conclusion is operational context as the product meets the design & manufacture specification but due to anatomical/procedural factors encountered during the procedure, performance was limited.(b)(4).
