Device evaluated by mfr: returned product consisted of the proximal portion of the quantum maverick balloon.Portion of the hypotube, the distal shaft, the balloon, the markerbands, and the tip were not returned for product analysis.The shaft, hypotube, and bonds were microscopically and visually examined.There was also, a complete hypotube separation 79.5cm from the strain relief.The hypotube fracture surface was ovaled, which suggests the device was kinked prior to separation.The shaft and bonds could not be analyzed as there were not returned for analysis.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.No other issues were identified during the product analysis.Device analysis determined the condition of the returned device was consistent with the reported information.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).
