1. Endoprosthesis furnished with an armature made of metal wires, the wires forming the armature, each wire comprising a core made of a radiopaque material, wherein;
- the armature is formed of at least two layers of wires;
these at least two layers of wires, viewed laterally, take the form of a three-dimensional stack of superposed windows mutually offset in space and offer, in perspective, the appearance of a series of pyramidal frusta, andthe diameter of the core of a wire does not exceed 13 μ
m, the interaction between the cores of the wires of the various layers causes said endoprosthesis to be visible in X-ray medical imaging.

12. An endoprosthesis having an armature made of a plurality of metal wires, the wires forming the armature, with each wire comprising a core made of a radiopaque material,
wherein the armature includes at least two layers of wires, which when viewed laterally, take the form of a three-dimensional stack of superposed windows mutually offset in space and offer, in perspective, the appearance of a series of pyramidal frusta, and wherein the diameter of the core of a wire does not exceed 25 μ - m, whereby the interaction between the cores of the wires of the various layers causes the endoprosthesis to be visible in X-ray medical imaging.

14. An endoprosthesis, comprising:
-
a first layer of metal wires; and a second layer of metal wires, wherein the second layer of metal wires is stacked on the first layer of metal wires in a position that is laterally offset relative to a position of the first layer of metal wires, wherein each wire included in the first layer of metal wires and each wire included in the second layer of metal wires includes a core made of radiopaque material that has a diameter that does not exceed 13 μ
m, andwherein the endoprosthesis is visible in X-ray medical imaging based on the cores of the wires of the first layer of metal wires and the cores of the wires of the second layer of metal wires appearing as a series of pyramidal frusta.
