  • Patent number: 9668893
    Abstract: The invention relates to an intravascular functional element with a tubular grid structure (12) that has a wire (10) or several wires (10) respectively of an alloy with nickel and titanium as alloying elements, wherein a mixed oxide layer with a layer thickness of 15 nm to 100 nm and containing TiO2 and at least one nitride, especially titanium oxynitride and/or titanium nitride, is formed on the surface of the wire or on the surface of the wires (10)/of the wires (10), wherein the grid structure forms cells of mutually crossing wires (10) or wire segments of the wire (10) in longitudinal direction and in circumferential direction respectively and in circumferential direction there are disposed at least 6 cells, especially at least 12 cells, especially at least 16 cells, especially at least 24 cells, especially at least 36 cells, especially at least 48 cells.

  • Patent number: 9561120
    Abstract: The invention relates to a method of manufacture of an intravascular functional element that can be introduced into a hollow organ and that comprises at least one wire (10) of an alloy having nickel and titanium as alloying elements, with the following steps: preparation of a metal body of the wire (10) with a metallic surface, then formation of a first oxide layer on the metallic surface of the metal body, then performance of a heat treatment of the wire (10) in a nitrogen-containing salt bath for thermal formation of a second mixed oxide layer on the first oxide layer, wherein the total layer thickness is 15 nm to 100 nm and the mixed oxide layer contains TiO2 and at least one nitride, especially titanium oxynitride and/or titanium nitride.
