  • Patent number: 8828474
    Abstract: Methods and apparatus are disclosed for loading a therapeutic substance or drug within a lumenal space of a hollow wire having a plurality of side openings along a length thereof that forms a hollow drug-eluting stent with a plurality of side drug delivery openings. Loading a drug within the lumenal space of the hollow stent includes a drug filling step, in which the drug is mixed with a solvent or dispersion medium. The lumenal space may be filled with the drug solution or suspension in a reverse fill process and/or a forward fill process. After the drug filling step, a solvent or dispersion medium extracting step is performed to extract the solvent or dispersion medium from within the lumenal space such that only the drug remains within the hollow stent. A stent cleaning step may be performed to an exterior surface of the hollow stent.

  • Patent number: 8728562
    Abstract: A method of manufacturing a medical electrical lead includes molding a lead body pre-form, stringing an electrode onto the pre-form and overmolding the pre-form with a polymer to form a lead body portion. The pre-form has a proximal end, a distal end and at least one lumen extending between the proximal and distal ends. At least one asymmetric region of the pre-form has a transverse cross-section that has a non-circular outer dimension. The overmolding causes the asymmetric region to become substantially circular.

  • Patent number: 8703247
    Abstract: A cross section processing method to be performed on a sample by irradiating the sample having a layer or a structure of an organic substance on a surface at a cross section processing position thereof with a focused ion beam using a focused ion beam apparatus includes: a protective film forming step for forming a protective film on the surface of the layer or the structure of the organic substance by irradiating the surface of the sample including the cross section processing position with the focused ion beam under the existence of source gas as the protective film; and a cross section processing step for performing cross section processing by irradiating the cross section processing position formed with the protective film with the focused ion beam at a voltage higher than an accelerating voltage in the protective film forming step.

  • Patent number: 8632844
    Abstract: A method for manufacturing a nerve regeneration-inducing tube with excellent pressure resistance, shape recovery property, anti-kink property, film exfoliation resistance, resistance to invasion of outer tissues, and leakage resistance. The tubular body is formed by weaving together fibers made up of biodegradable polymer. The outer surface of the tubular body is coated multiple times with a collagen solution. The lumen of the tubular body is filled with collagen. Viscosity of the collagen solution that is first applied to the outer surface of the tubular body is between 2 to 800 cps. Viscosity of the collagen solution that is subsequently applied is higher than viscosity of the first applied collagen solution.

  • Patent number: 8580339
    Abstract: A coating process for the interior of a pipework system, which includes a subsystem having a first part-system and a second part-system coupled to the first part-system, wherein the part-system can be pressurized by a pressure difference via a first connection of the first part-system and via a second connection of the second part-system, and wherein the first connection of the second part-system is identical to the second connection of the first part-system. In a second process step the first part-system is pressurized in such a way that a fluid-flow of the coating material is established through the first part-system and then the first connection of the second part-system is pressurized after the coating material leaves the second connection of the first part-system so that the first part-system and the second part-system is consecutively fed with the coating material.

  • Patent number: 8440266
    Abstract: A developer nozzle supplies a developer onto the surface of a substrate rotating around a vertical axis, while a pure water nozzle supplies pure water onto the surface of the rotating substrate. The pure water nozzle is spaced apart from the developer nozzle and located on an outer side of the substrate with respect to the developer nozzle. The pure water restricts flow of the developer on the substrate and causes the developer to spread toward a clockwise side of the substrate when the substrate rotates in a clockwise direction. A liquid film containing the developer and the pure water is formed on the substrate. The developer nozzle and the pure water nozzle are spaced apart from each other to suppress splattering of the developer and the pure water due to collision of the developer with the pure water.
