  • Publication number: 20110033335
    Abstract: One aspect is a method for producing an alloy, whereby the alloy includes at least a first metal and a second metal, whereby firstly a powder metallurgical route and subsequently a melt metallurgical route is used sequentially in order to generate the alloy from the, at least, first metal and the second metal. The method includes grinding the first metal into a first metal powder, grinding the second metal into a second metal powder, mixing the first metal powder and the second metal powder to produce a blended powder, generating a blended body from the blended powder by the powder metallurgical route, and generating the alloy by melting the blended body by the melt metallurgical route.

  • Publication number: 20100222866
    Abstract: The present invention relates to a medical device or implant made at least in part of a high strength, low modulus metal alloy comprising Niobium, Tantalum, and at least one element selected from the group consisting of Zirconium, Tungsten, and Molybdenum. The medical devices according to the present invention provide superior characteristics with regard to bio-compatibility, radio-opacity and MRI compatibility.

  • Publication number: 20100211147
    Abstract: One aspect is a stranded wire containing numerous coils. The stranded wire is configured as an electrical connection between an electrical stimulation device that is connected to the proximal end of the stranded wire, and an electrode connected to the distal end of the stranded wire. At least one coil includes a tantalum or niobium-based metal.

  • Patent number: 6610086
    Abstract: A radially expandable support structure is presented, for keeping open lumina within a body, in particular a blood vessel, having a tube-shaped structure that has at least two partial structures, with a wall surface that extends between a first and a second end, which has several cut out areas, in particular, slits, which are essentially oriented parallel to the longitudinal axis of the tube-shaped structure. At least one of the partial structures (11) extend without interruption in the axial direction generally from the first end to the second end of the tube-shaped structure. A first partial structure (1, 2) can be expanded at least in the radial direction and has at least one radial-expansion component. The individual radial expansion components (12, 13) are arranged as a helix or in a helix shape. A second partial structure (11) is generally almost rigid in the axial direction.
