摘要
There is a stent (110) for implantation in a cavity (112) of a human or animal body and a method for producing an X-ray-opaque layer structure (138) on a stent (110) for implantation in a cavity (112) of a human or animal body suggested. The stent (110) comprises at least one tubular hollow body (116), the tubular hollow body (116) having at least one surface (136), the surface (136) being completely coated with an X-ray-opaque layer structure (138), which comprises a plurality each have layers (142) lying one above the other, the layers (142) each being made of at least one metal which has an atomic number from 22 to 83, the layers (142) each having a layer thickness d in the range from 1 nm to 400 nm .
