摘要： A multiple-sided medical device comprises a frame comprising wire or other resilient material and having a series of bends and interconnecting sides. The device has both a flat configuration and a second, folded configuration which a generally serpentine shape. The device is pushed from a delivery catheter into the lumen of a duct or vessel and may include one or more barbs for anchoring purposes. A full or partial covering of fabric or other flexible material such as DACRON, PTFE, or a collagen-based material such as small intestinal submucosa (SIS), may be sutured or attached to the frame to form an occlusion device, a stent graft, or an implantable, intraluminal valve such as for correcting incompetent veins in the lower legs and feet.

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.
