Raymond Victor Froehlich 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).

  • Ablation system, methods, and controllers
    Patent number: 10918434
    Abstract: Multi-electrode ablation systems, methods, and controllers are described. In one example, a multi-electrode ablation system includes a power supply configured to be coupled to a plurality of electrodes and a controller coupled to the power supply. The controller is configured to determine a thermal gain of each electrode of the plurality of electrodes. For each electrode of the plurality of electrodes, the controller sets a power limit based at least in part on said electrode's determined thermal gain. The power limit establishes a maximum power that may be dissipated through said electrode.
    Type: Grant
    Filed: May 3, 2018
    Date of Patent: February 16, 2021
    Assignee: ST. JUDE MEDICAL, CARDIOLOGY DIVISION, INC.
    Inventors: John B. Blix, James C. Baker, Kevin K. Ennett, John Eric Hein, Joseph Allen Brotz, Joseph William Barnier, Raymond Victor Froehlich, Michael Olsen, Sukanya Varadharajan
