    摘要: Medical devices, such as endoprostheses, and methods of making the devices are disclosed. The endoprostheses comprise a tubular member capable of maintaining patency of a bodily vessel. The tubular member includes a mixture of at least two compositions, where the presence of the second composition gives the mixture a greater hardness than that of the first composition alone. The first composition includes less than about 25 weight percent chromium, less than about 7 weight percent molybdenum, from about 10 to about 35 weight percent nickel, and iron. The second composition is different from the first and is present from about 0.1 weight percent to about 5 weight percent of the mixture.

    摘要: An endoprosthesis can have a member that includes molybdenum and at least one metal selected from the group consisting of titanium, rhenium, yttrium, palladium, rhodium, ruthenium, tungsten, tantalum, iridium, zirconium, hafnium, niobium, chromium, and combinations thereof. The member can have a microstructure characterized by: (a) a molybdenum-rich base region comprising at least 50 weight percent molybdenum, (b) a surface region comprising at least one metal selected from the group consisting of titanium, rhenium, yttrium, palladium, rhodium, ruthenium, tungsten, tantalum, iridium, zirconium, hafnium, niobium, chromium, and combinations thereof, and (c) an inter-diffusion region in which the concentration of molybdenum decreases in the thickness direction from the molybdenum-rich base region to the surface region of the member.
