Abstract

An abdominal aortic stent includes a first sub-stent and a second sub-stent each having a front end. The circumference of the front end of each sub-stent is half of the circumference of the abdominal aorta. When the circumference is gradually reduced to a rear end of each sub-stent, it has entered one side of the bilateral femoral arteries. The rear ends of the sub-stents with full circumference of the cross-sectional area of the femoral artery are included therein. The first and second sub-stents are coated with external removable membrane to compress the sub-stents to generate smaller circumferences. When the removable membrane has been removed, the sub-stents are fully extended to reconstruct the vascular flow path.
