  • METHOD TO PREVENT METAL CONTAMINATION BY A SUBSTRATE HOLDER
    Publication number: 20200017952
    Abstract: Method to increase the wettability of a substrate by providing the substrate at least partially with a conductive, metal free, hydrophilic carbon based coating. The carbon based coating is doped with nitrogen and has an electrical resistivity lower than 108 ohm-cm. An adhesion promoting layer is applied on the substrate before the application of the carbon based coating. The adhesion promoting layer includes at least one element of the group consisting of silicon and of the elements of group IVB, the elements of group VB and the elements of Group VIB of the periodic table, wherein the carbon based coating includes a nitrogen doped diamond-like carbon (DLC) coating of amorphous hydrogenated carbon (a-C:H) and a nitrogen doped diamond-like nanocomposite (DLN) coating comprising C, H, O and Si.

  • Intravascular stent with expandable coating
    Patent number: 7300461
    Abstract: An intravascular stent (26) has a surface coated with a biocompatible layer. The layer contains a diamond like nanocomposite material. This nanocomposite material comprises carbon, hydrogen, silicon and oxygen as constituent elements. The layer has a stress which is less than 150 MPa in order to ensure a high degree of flexibility and a complete expandability. This lower stress is obtained by the inclusion of relatively large amounts of Si:O bonds. In a preferable embodiment the layer with diamond like nanocomposite material covers the stent (26) for 100%. This is obtained by allowing the stent to move freely along a wire during CAVD deposition.
