SYSTEMS AND METHODS FOR TREATING TISSUE WITH PULSED FIELD ABLATION

Pulsed field ablation systems are disclosed, some of which may include an output pulse generation circuit and a high voltage pulse generation circuit electrically connected to the output pulse generation circuit. The high voltage pulse generation circuit may be configured to deliver a high voltage pulse set to the output pulse generation circuit. The output pulse generation circuit may be configured to generate an output pulse set at least in response to the high voltage pulse set. The output pulse set may be deliverable to a set of selectable electrodes and may be configured to cause pulsed field ablation of tissue. Each pulse in the output pulse set may have a rise time that is shorter than a rise time of at least one high voltage pulse in the high voltage pulse set.
