Patents by Inventor John F. Hartnett

John F. Hartnett 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).

  • Polymeric implements for torque transmission
    Patent number: 6436056
    Abstract: Implements, particularly medical instruments, formed at least in part of elongated polymer members, exhibit high torque fidelity after processing with tension, heat, and twisting. The processing orients the polymer in generally helical paths so that torque imposed at the proximal end can be transmitted to the distal end without substantial whipping, even if the implement follows a long and tortuous pathway. Applications include medical guidewires, catheters, and driveshafts.
    Type: Grant
    Filed: July 13, 1998
    Date of Patent: August 20, 2002
    Assignee: Boston Scientific Corporation
    Inventors: James C. Wang, Albert Chin, James B. Daigle, Douglas J. Daniels, Richard M. Demello, John F. Hartnett, Robert E. Reid, Christopher A. Rowland, Charles Warich, Thomas A. Svatek
