    摘要： Improved endoluminal prostheses and methods for their use, having discrete position indicating elements which facilitate the orienting and deploying of the prostheses within body lumens. The endoluminal prostheses may include endovascular prostheses, often formed as stent-grafts having a flexible tubular liner or “graft.” The position indicating elements may include an improved radiopaque image marker to be applied to the graft, before the graft is deployed particularly within branching blood vessels for the treatment of abdominal and other aneurysms. The marker is in the form of a flat metal blank resembling a circular plate or “button.” The disk may be fastened or secured on to the graft using a pair of fastening shanks or tangs which extend parallel to each other outward from a surface of the plate.

    摘要： Endoluminal prostheses, prosthetic systems, and methods for preparation and use of endoluminal prostheses for treatment of diseased body lumens make use of endoluminal prosthetic frame structures having circumferentially interspersed large and small expansible elements. These expansible elements, which are typically diamond-shaped, will generally decrease in length as the tubular frame expands radially. The prosthesis will often include a tubular liner supported by an axial series of ring frames having alternating large and small diamond elements, and can be loaded in a delivery catheter with the axial apices of the large diamond-shaped elements aligned with a small diamond-shaped element of an adjacent frame ring. To maintain adequate column strength, the adjacent ring frames may be attached to the liner so that the ring frames rotate relative to each other during expansion. The large diamond-shaped elements of adjacent ring frames can be aligned together once the prosthesis is expanded in the body lumen to enhance column strength.
