Patents by Inventor William Pippey

William Pippey 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: 10525552
    Abstract: The present invention involves laser machining polymer substrates to form a stent with laser parameters that minimize damage to the substrate in a surface region adjacent to the machined edge surface. The wavelength and pulse width are selected for this unique application and they can be controlled to minimize the surface modifications (such as voids, cracks which are induced by the laser-material interaction) which contribute to the variation in mechanical properties with distance from the edge surface, bulk mechanical properties, or a combination thereof.
    Type: Grant
    Filed: July 6, 2017
    Date of Patent: January 7, 2020
    Assignee: ABBOTT CARDIOVASCULAR SYSTEMS INC.
    Inventors: Joel Harrington, Ryan Vaughan, Kevin Jow, William Pippey, Yung-Ming Chen
