Patents by Inventor Samuel P. Baldwin

Samuel P. Baldwin 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: 7507772
    Abstract: Chemically cross-linked polymeric particles are formed using mechanical rather than chemical processes, facilitating production of small-diameter particles in a manner largely independent of the viscosity or density of the polymer. For example, an uncross-linked resin may be provided in particulate form, agglomerated, and compressed into a mass of a desired shape with a desired diameter, and subsequently cross-linked.
    Type: Grant
    Filed: September 12, 2007
    Date of Patent: March 24, 2009
    Assignee: Boston Scientific Scimed, Inc.
    Inventors: Samuel P. Baldwin, Robert P. Skribiski

  • Patent number: 7094369
    Abstract: Processes of manufacturing polymeric microspheres facilitate the generation of polymeric microspheres of size ranges smaller than 600 microns diameter by forming beads of a predetermined size from a starting material which may include a template polymer, and subsequently contacting the beads with a structural polymer. After crosslinking of the structural polymer has taken place, the template polymer may be removed to form the finished microspheres.
