(b)(4).Returned product consisted of a quantum maverick balloon catheter.The balloon was loosely folded.The outer shaft, inner shaft, balloon and tip were microscopically examined.The hypotube shaft was completely separated 93.4cm from the hub.The fracture faces were oval as if kinked prior to separation.There was no evidence of any material or manufacturing deficiencies contributing to the damage.There were numerous hypotube and shaft kinks.The most probable root cause is operational context as device performance was limited due to anatomical/procedural factors.(b)(4).

Reportable based on device analysis completed on 06-oct-2017.It was reported that shaft kink occurred.The 80-100% stenosed target lesions were located in the left anterior descending artery, first diagonal artery and left circumflex artery.A 3.5mm x12mm quantum¿ maverick¿ was advanced for dilatation.However during the procedure, it was noted that the shaft got kinked.The procedure was completed with a different device.No patient complications were reported and the patient's status was stable.However, returned device analysis revealed hypotube break.
