An international customer reported that during an endovascular aneurysm repair (evar) via femoral approach, an unspecified stent graft was placed in the patient.Then a non-cook stent was placed in the iliac artery to reinforce the leg of the stent graft.Post-dilation of the non-cook stent was conducted first with an advance 35 lp low profile balloon catheter, which was used without any problem.Then, the physician dilated the lesion further with a larger-diameter balloon.The advance 35 lp low profile balloon catheter was advanced to the target site and inflation was attempted.However, the balloon would not inflate well and ruptured at nominal pressure.It was replaced with another unspecified balloon and the procedure was completed successfully.There were no adverse effects to the patient.Further information has been requested.
