Abstract
A pulse phase ablation biphasic PFA generator with finite energy source and delivery mechanism is disclosed, comprising: a signal source configured to output electrode input signals; a trigger circuit configured to trigger signals; at least one electrode channel circuit including a charge transfer source circuit including a source capacitor and coupled to the signal source to receive the electrode input signals, the charge transfer source circuit being configured to charge the source capacitor to a source voltage, a switching circuit coupled to charge transfer source circuit to receive the source voltage and to the trigger circuit to receive the trigger signals, and a charge transfer load circuit including a load capacitor coupled to the switching circuit; wherein the switching circuit further includes a plurality of spark gap switches activated by the trigger signals to cause the electrode channel to apply a biphasic waveform to electrodes configured to contact tissue.
