Corinne WEYRAUCH 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).

  • Tissue contact sensing with a multi electrode ablation catheter
    Patent number: 10182742
    Abstract: A method and system for assessing electrode-tissue contact before the delivery of ablation energy. The system may include a control unit programmed to determine a difference between a maximum impedance magnitude at a low frequency for a given electrode and an absolute minimum impedance magnitude at the low frequency across all electrodes, determine a difference between a maximum impedance magnitude at a high frequency for a given electrode and an absolute minimum impedance magnitude at the high frequency across all electrodes, and determine a difference between a maximum impedance phase at the high frequency for a given electrode and an absolute minimum impedance phase at the high frequency across all electrodes. Differences may be correlated to one another using a linear model, the results determining electrode-tissue contact status. The results may be displayed in a graphical format for easy communication to the user.
    Type: Grant

  • Tissue contact sensing with a multi electrode ablation catheter
    Patent number: 10143399
    Abstract: A method and system for assessing electrode-tissue contact before the delivery of ablation energy. The method may generally include determining a difference between a maximum impedance magnitude at a low frequency for a given electrode and an absolute minimum impedance magnitude at the low frequency across all electrodes, determining a difference between a maximum impedance magnitude at a high frequency for a given electrode and an absolute minimum impedance magnitude at the high frequency across all electrodes, and determining a difference between a maximum impedance phase at the high frequency for a given electrode and an absolute minimum impedance phase at the high frequency across all electrodes. These differences may be correlated to one another using a linear model, the results of which determining whether the given electrode is in contact or not in contact with tissue.
