Manufacturer Narrative

Based on the initial details provided the balloon was slowly inflated and deflated.When the balloon was re-inflated the balloon ruptured and upon withdrawal of the balloon back through the sheath the balloon inverted on itself and separated from the catheter shaft.Based on the follow-up details provided it appears as the stent was not deployed and considering the original complaint description where as the balloon was inflated contradicts this statement.Being that this case was a 4 vessel fenestrated case it is clear that the icast covered stent would have had to been navigated through the endograft as part of the procedure.This also contradicts the response to question #6 "did the device advance through any other grafts or stents?" the response was "no".If the renal artery was the target during the fenestrated case the icast covered stent would have had to navigate through the endograft at a minimum and through the fenestration of the endograft.Some endografts have fixation barbs to anchor the endograft into the aortic tissue.If the balloon of the icast covered stent were to make even the slightest contact with one of the fixation barbs, the balloon would rupture as the fixation barbs are laser sharpened.As there are no fluoroscopic images from the procedure a determination of the cause of the balloon rupture or burst was not able to be determined as only a small portion of the catheter was returned.A review of the device history records was conducted.The review shows that there were no non-conformances during the manufacture of the product and that all quality and performance requirements were met, including balloon burst testing to rated burst pressure.Based on the details of the complaint and the investigation results including the dhr review, the complaint cannot be confirmed.Additionally, there is no evidence to conclude that the device was deficient.It is likely that the balloon either made contact with a fixation barb of the endograft and or ruptured on a calcified lesion as the details indicate that the lesion was calcified.This cannot be confirmed however without fluoroscopic imaging from the case.Based on the results of the investigation the product met all specifications.The product was being used for treatment or diagnosis at the time when the event occurred.The device was directly involved in the reported incident.As the provided details indicate the icast covered stent was used in a 4 fenestrated endograft case within a lesion that was tortuous and calcified the most probable root cause is operational context.
