  • Systems and methods for limiting arcing in electroporation systems
    Patent number: 12383331
    Abstract: The present disclosure provides methods and systems for limiting arcing during an electroporation procedure. A method includes delivering a calibration shock using a catheter, measuring a current delivered during the calibration shock and a voltage delivered during the calibration shock, calculating, using a processing device, a calibration shock impedance based on the delivered current and the delivered voltage, calculating, using the processing device, a bridge impedance based on the calibration shock impedance and a target impedance, wherein the bridge impedance is a difference between the calibration shock impedance and the target impedance, adding an impedance in series with the catheter, the impedance being greater than or equal to the bridge impedance, and delivering a therapeutic shock using the catheter in series with the added impedance.
    Type: Grant
