Abstract
A single-piece bifurcated graft for insertion into the femoral artery and further into the aorta with approximately one half of the graft inverted inside out after positioning within the artery. There is no central section like other bifurcated grafts. Instead, two bifurcated sections are joined at the top. Upon introduction, the graft is attached to the aortic wall in the middle section, the vicinity of the renal arteries, and the inversion process takes place. This process allows deployment of the second half of the graft into its final inverted position. While stents are located only at the openings of the graft, additional stents may be deployed inside the graft if necessary.
