  • Radiation sterilization of medical devices
    Publication number: 20070280851
    Abstract: Methods and systems for selection radiation exposure in sterilization of medical devices are disclosed.
    Type: Application
    Filed: May 15, 2007
    Publication date: December 6, 2007

  • Self-aggregating protein compositions and use as sealants
    Patent number: 7241309
    Abstract: There is described a bio-compatible aqueous slurry for forming a fluid-tight barrier on a surface of a porous implantable article. This aqueous slurry includes a self-aggregating protein comminutate having a substantially uniform particle size, a bio-compatible plasticizer and water. This aqueous slurry is further characterized by having a viscosity of about 8,000 centipoise to about 60,000 centipoise at 25° C. and a pH sufficient to maintain the protein suspended in the slurry.
    Type: Grant
    Filed: June 8, 2001
    Date of Patent: July 10, 2007
    Assignee: Scimed Life Systems, Inc.

  • Self-aggregating protein compostions and use as sealants
    Publication number: 20050085901
    Abstract: An implantable member for use in the body is provided herein. This implantable member includes a porous biocompatible substrate; the substrate having at least one surface sealed fluid-tight with self-aggregating protein particles of substantially the same diameter range. The self-aggregated protein particles are formed from a deposited aqueous slurry of the protein particles.

  • Method of forming lubricant films
    Patent number: 6849304
    Abstract: Thin lubricant films are prepared on optical and magnetic substrates by applying a lubricant having at least one UV polymerizable group onto the substrate and polymerizing the lubricant by UV irradiation at elevated temperatures. Embodiments include applying a lubricant having at least two acrylate groups onto a magnetic recording disc, heating the magnetic recording disc from about 50° C. to about 150° C. and exposing the lubricant to UV radiation substantially free of wavelengths of 200 nm or less.
