Abstract
A method of determining a pulsed field ablation waveform parameter for creating a desired lesion characteristic in cardiac tissue. The method of provides an electrosurgical generator configured to deliver electroporation pulses, the generator configured to: load predetermined waveform parameters (yi); load predetermined modeling data (xi); accept entry of a user inputted desired lesion characteristic (ui); and determine at least one corresponding pulsed field ablation waveform parameter based on (ui), (yi); and (xi).
Claims8
An electrosurgical generator configured to deliver pulsed field ablation pulses to electroporate cardiac tissue, the electrosurgical generator comprising:
- a processor having processing circuitry configured to:
- load predetermined waveform parameters (yi);
- load predetermined modeling data (xi);
- accept entry of a user inputted desired lesion characteristic (ui);
- and
- select at least one waveform parameter (y) from the loaded predetermined waveform parameters (yi), the selecting being based on a statistical significance of the waveform parameter (y) in determining the user inputted desired lesion characteristic (ui), the statistical significance being indicated from experimental modeling;
- determine at least one pulsed field ablation waveform parameter corresponding to the selected at least one waveform parameter (y), based on (ui) and (xi).
