    Abstract: The present disclosure relates generally to coating medical devices. In particular, the present disclosure provides materials and methods for coating a portion of a balloon catheter with a pharmaceutical agent using electrodeposition techniques. Although angioplasty and stenting can be effective methods for treating vascular occlusions, restenosis remains a pervasiveness problem. Therefore, coating portions of a balloon catheter with a pharmaceutical agent that inhibits restenosis can reduce the likelihood of restenosis.

  • Patent number: 8846537
    Abstract: A mold having an open interior volume is used to define patterns. The mold has a ceiling, floor and sidewalls that define the interior volume and inhibit deposition. One end of the mold is open and an opposite end has a sidewall that acts as a seed sidewall. A first material is deposited on the seed sidewall. A second material is deposited on the deposited first material. The deposition of the first and second materials is alternated, thereby forming alternating rows of the first and second materials in the interior volume. The mold and seed layer are subsequently selectively removed. In addition, one of the first or second materials is selectively removed, thereby forming a pattern including free-standing rows of the remaining material. The free-standing rows can be utilized as structures in a final product, e.g., an integrated circuit, or can be used as hard mask structures to pattern an underlying substrate. The mold and rows of material can be formed on multiple levels.

  • Patent number: 8821958
    Abstract: A method for electrostatic coating of medical devices such as stents and balloons is described. The method includes applying a composition to a polymeric component of a medical device which has little or no conductivity. The polymeric component could be a material from which the body or a strut of the stent is made or could be a polymeric coating pre-applied on the stent. The polymeric component could be the balloon wall. A charge can then be applied to the polymeric component or the polymeric component can be grounded. Charged particles of drugs, polymers, biobeneficial agents, or any combination of these can then be electrostatically deposited on the medical device or the coating on the medical device. One example of the composition is iodine, iodine, iodide, iodate, a complex or salt thereof which can also impart imaging capabilities to the medical device.

  • Publication number: 20140231718
    Abstract: A process for producing a transparent conductive film, comprising (a) providing a graphene oxide gel; (b) dispersing metal nanowires in the graphene oxide gel to form a suspension; (c) dispensing and depositing the suspension onto a substrate; and (d) removing the liquid medium to form the film. The film is composed of metal nanowires and graphene oxide with a metal nanowire-to-graphene oxide weight ratio from 1/99 to 99/1, wherein the metal nanowires contain no surface-borne metal oxide or metal compound and the film exhibits an optical transparence no less than 80% and sheet resistance no higher than 300 ohm/square. This film can be used as a transparent conductive electrode in an electro-optic device, such as a photovoltaic or solar cell, light-emitting diode, photo-detector, touch screen, electro-wetting display, liquid crystal display, plasma display, LED display, a TV screen, a computer screen, or a mobile phone screen.

  • Patent number: 8747956
    Abstract: Processes, systems, and apparatuses are disclosed for forming products from atomized metals and alloys. A stream of molten alloy and/or a series of droplets of molten alloy are produced. The molten alloy is atomized to produce electrically-charged particles of the molten alloy by impinging electrons on the stream of molten alloy and/or the series of droplets of molten alloy. The electrically-charged molten alloy particles are accelerated with at least one of an electrostatic field and an electromagnetic field. The accelerating molten alloy particles are cooled to a temperature that is less than a solidus temperature of the molten alloy particles so that the molten alloy particles solidify while accelerating. The solid alloy particles are impacted onto a substrate and the impacting particles deform and metallurgically bond to the substrate to produce a solid alloy preform.
