It was reported that the procedure was to treat an aorta bifurcation.An 8x40mm armada 35 balloon was advanced to the lesion and was inflated 1-2 times at 8 atmospheres (atms) when it ruptured and a piece (around 1 to 2mm length) of balloon released in the artery.Another 8x40mm armada 35 balloon was inflated once and burst at 8 atms.It was decided to attempt to retrieve the balloon portion that separated from the first armada 35 but it wasn't possible.Therefore, a stent was used to embed the separated balloon piece to the vessel wall.The patient was transferred to the intensive care unit afterwards.On day 4, the patients clinical condition was hemodynamically good.There was no adverse patient sequela and no clinically significant delay.No additional information was provided.

A visual analysis and a scanning electron microscopy (sem) analysis were performed on the returned unit.The balloon rupture and separation were confirmed.A review of the lot history record revealed no manufacturing nonconformities that would have contributed to this complaint.Additionally, a review of the complaint history of the reported lot revealed no other similar complaints.Based on the information provided, the balloon rupture and separation appear to be due to case circumstances.It is likely that the balloon rupture and subsequent separation occurred due to interaction with the calcified lesion causing damage to the outer surface of the balloon material leading to the rupture and separation.The additional therapy to attempt removal and embed the separated portion was due to the case circumstances.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
