An aortoiliac endoprosthesis including two tapering tubes (2a) capable of being bent in all directions so that the upper tube ends (2b) have a greater diameter than the lower tube ends (2c), while sleeves (3, 4) are secured to each of the ends (2b, 2c). The sleeves (3, 4) are provided with hook means (5) for retaining the endoprosthesis (2), and made of a biocompatible, flexible shape-memory metal material.
