  • Publication number: 20080215132
    Abstract: Textured coatings for implantable medical devices can be provided in metallic or polymer surface layers having surface texture factors down to nanometer and sub-nanometer levels. Implantable devices having such textured surfaces and methods of coating such devices comprises providing a substrate surface of an implantable device and forming a coating layer of the substrate surface by directing a mixture of atoms of a first type of material and a second type of material toward the substrate surface while simultaneously and collinearly bombarding the substrate surface with ions, wherein the first type of material is substantially resistant to a removal process and the second type of material is substantially susceptible to a removal process.

  • Publication number: 20080177371
    Abstract: An implantable device and method of forming the same comprises a substrate, an adhesion layer, and a capping layer. The adhesion layer comprises a portion with a predominant proportion of palladium, the portion of the predominant proportion of palladium directly on the substrate. The capping layer comprises a capping layer material, and is on the adhesion layer.

  • Publication number: 20060260930
    Abstract: Intravascular devices having a radiopaque layer thereon for visualization are provided. The devices further includes a capping layer on the radiopaque layer to prevent exposure of the radiopaque material to surrounding tissues. A method of coating the device is also provided. The method includes using an unbalanced magnetic field magnetron to generate, from a source, metal atoms for coating and bombarding ions for compressing deposited metal atoms to the surface of the device.

  • Patent number: 6299438
    Abstract: A dental article coated with a friction-reducing coating and methods for coating dental articles are disclosed. In one embodiment, the dental device first is coated with an adhesion layer, followed by application of a friction-reducing coating. The friction-reducing coating is selected to create a hard, inert, friction-reducing layer on the device. The presence of the continuous outer coating of on the device reduces adhesive wear and friction on the device, and significantly improves its frictional properties.
