    Abstract: Methods and systems for coating at least a portion of a medical device (e.g., a stent structure) include providing a plurality of coating particles (e.g., monodisperse coating particles) in a defined volume. For example, the particles may be provided using one or more nozzle structures, wherein each nozzle structure includes at least one opening terminating at a dispensing end. The plurality of coating particles may be provided in the defined volume by dispensing a plurality of microdroplets having an electrical charge associated therewith from the dispensing ends of the one or more nozzle structures through use of a nonuniform electrical field between the dispensing ends and the medical device. Electrical charge is concentrated on the particle as the microdroplet evaporates. With a plurality of coating particles provided in the defined volume, such particles can be moved towards at least one surface of the medical device to form a coating thereon (e.g., using an electric field and/or a thermophoretic effect).

    Abstract: In a method of applying a firmly adhering metallic coating onto a profiled structure of steel sheet, a profiled structure of steel sheet is fogged in with metal powder in a treatment chamber. The metal powder is deposited electrostatically across the surface of the profiled structure. The profiled structure is then subjected to a heat treatment for realizing a coating as a consequence of a diffusion process between the steel sheet and the metal powder. Subsequently, the profiled structure is cooled down.

    Abstract: A method and apparatus for providing a pattern on a solid dosage form, in which powder material is applied in a pattern to a substrate. A mask having an aperture is provided between a source of the powder material and the substrate and the powder material is applied to the substrate through the mask. Relative movement of the substrate with respect to the source of powder material is effected during the pattern application process.

    Abstract: A method and a device for contactless application of a coating on a three dimensionally distributed surface (14;24;34;44;54;74;84;104). The method comprises application of electrically charged particles (15;25;35;55;65;75;85;105) in such positions on said surface as to form a predetermined pattern, by guiding each of said particles individually to a predetermined position on said surface. The guiding is made by means of an adjustable electric field (12;22;32;42;52;72;82;102) having flux lines with a longitudinal direction extending through said surface, whereby said particles form said coating according to said predetermined pattern on said surface.

    Abstract: The invention relates to a device for producing singlet oxygen, comprising a housing forming a chamber which has at least two opposite surfaces. One of said surfaces is transparent and the other is covered by a coating made from a dye excitable by light, and a light source for irradiating the surface covered with the dye. The surface covered with the dye is formed by a substrate comprising a finely roughened surface. The dye is introduced into the indentations of the finely roughened surface by polishing. The light source can be formed by light emitting diodes, whose light emission comprises a wavelength located within the range of maximum radiation absorption of the dye of the coated surface.
