  • Publication number: 20070255140
    Abstract: An ultrasonically visible solid device for inserting into a non-gas target medium comprises an echogenic surface having structures entrapping gas when the device is in the target medium, the entrapped gas causing the device to be ultrasonically visible, wherein the gas-entrapping structures are covered with a flexible overcoat that does not significantly reduce the compressibility of the gas trapped in the structures.
    Type: Application
    Filed: April 25, 2007
    Publication date: November 1, 2007
    Applicant: Angiotech Biocoatings Corp.
    Inventors: Michael Violante, Richard Whitbourne, John Lanzafame, Margaret Lydon

  • Patent number: 6610016
    Abstract: Coatings to enhance the echogenicity of materials are especially useful for medical devices wherein the practitioner desires to locate or visualize a device by ultrasonic imaging when the device is inserted into a body cavity. These coatings can be applied to any device of virtually any composition. To accomplish this, a polymer matrix is formed containing an entrapped gas in enclosed bubbles or open surface channels or cavities. Coated needles are visible in ultrasound when inserted in animals. A pre-coat or base coat may be applied to condition the surface to enhance adhesion. A finish coat or top coat may be applied to improve durability, smoothness, and biocompatibility, lubricity, antibiotic, antimicrobial, antithrombogenic activity, and other desirable properties for the finished product. Coating liquids and methods for preparing and applying such coatings are disclosed, including forming bubbles by chemical reaction during the coating process.
