Patents by Inventor Jimmy C. Trevino

Jimmy C. Trevino 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).

  • Microvalve
    Patent number: 5819749
    Abstract: Micromachined thin film cantilever actuators having means for individually controlling the deflection of the cantilevers, valve members, and rudders for steering same through blood vessels, or positioning same within a blood vessel, for example. Such cantilever actuators include tactile sensor arrays mounted on a catheter or guide wire tip for navigation and tissues identification, shape-memory alloy film based catheter/guide wire steering mechanisms, and rudder-based steering devices that allow the selective actuation of rudders that use the flowing blood itself to help direct the catheter direction through the blood vessel. While particularly adapted for medical applications, these cantilever actuators can be used for steering through piping and tubing systems.
    Type: Grant
    Filed: July 22, 1997
    Date of Patent: October 13, 1998
    Assignee: Regents of the University of California
    Inventors: Abraham P. Lee, Peter A. Krulevitch, M. Allen Northrup, Jimmy C. Trevino
