(b)(4).Returned product consisted of a quantum maverick balloon catheter in two pieces.The balloon was loosely folded.There is contrast and blood on the balloon and in the guidewire lumen.The outer shaft, inner shaft, balloon and tip were microscopically examined.The hypotube was completely separated 42.5cm from the hub.The fracture faces were oval as if kinked prior to separation.There are numerous hypotube kinks.The tip is damaged.There is shaft damage at the exit notch that is consistent with damage seen with the use of a guidewire.There was no evidence of any material or manufacturing deficiencies contributing to the damage.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).
