摘要
An endovascular graft prosthesis for arrangement at an aneurysm positioned in the vicinity of a bifurcation in an arterial system having a main lumen and a first and a second branch lumen. The endovascular graft prosthesis includes a prosthetic device with at least one expandable tubular frame body for arrangement in the main lumen and a first and a second graft limb. The frame body is contractible into a first shape with a smaller diameter for introduction to a vascular site upstream of the aneurysm and is radially expandable into a second shape having a larger diameter and an inner lumen. The frame body is provided with a covering which extends across the inner lumen of the tubular frame body and has two apertures each of which has a diameter of less than half the larger diameter of the frame body. The first and second limbs have a cranial end for mounting at one of the apertures and a caudal end for arrangement in one of the branch lumens. The covering is a hindrance to blood flowing past the frame body except for blood flowing into the first and second graft limbs mounted at the two apertures.
