Patents by Inventor Leonard S Fifield

Leonard S Fifield has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10464100
    Abstract: A system and method are disclosed for coating surfaces of expandable medical devices with composite coatings. Coatings are composed of various materials including, e.g., polymers and drugs. Transfer of the coatings within a patient or other host forms a drug-eluting coating that delivers time-released drugs over time for treatment of a medical condition.
    Type: Grant
    Filed: May 30, 2012
    Date of Patent: November 5, 2019
    Assignees: Micell Technologies, Inc., Battelle Memorial Institute
    Inventors: Dean W. Matson, Clement R. Yonker, John L. Fulton, George S. Deverman, Barbara J. Tarasevich, Wendy J. Shaw, Leonard S. Fifield, Krys Wallace, C. Douglas Taylor, James B. McClain
  • Patent number: 9919264
    Abstract: A method for making a graphene oxide membrane and a resulting free-standing graphene oxide membrane that provides desired qualities of water permeability and selectivity at larger sizes, thinner cross sections, and with increased ruggedness as compared to existing membranes and processes.
    Type: Grant
    Filed: June 20, 2016
    Date of Patent: March 20, 2018

  • Patent number: 9499880
    Abstract: A system and process are disclosed for production of consolidated magnesium metal products and alloys with selected densities from magnesium-containing salts and feedstocks. The system and process employ a dialkyl magnesium compound that decomposes to produce the Mg metal product. Energy requirements and production costs are lower than for conventional processing.

  • Publication number: 20120107213
    Abstract: Methods of the present invention can be used to synthesize nanowires with controllable compositions and/or with multiple elements. The methods can include coating solid powder granules, which comprise a first element, with a catalyst. The catalyst and the first element should form when heated a liquid, mixed phase having a eutectic or peritectic point. The granules, which have been coated with the catalyst, can then be heated to a temperature greater than or equal to the eutectic or peritectic point. During heating, a vapor source comprising the second element is introduced. The vapor source chemically interacts with the liquid, mixed phase to consume the first element and to induce condensation of a product that comprises the first and second elements in the form of a nanowire.
