Abstract
Systems, devices, and methods for electroporation ablation therapy are disclosed, with the system including a signal generator for generating pre-ablation signals and pulse waveforms for medical ablation therapy that may be coupled to an ablation device including at least one electrode for ablation pulse delivery to tissue. The signal generator may generate and delivery pre-ablation signals to subsets of electrodes of the ablation device and measure currents associated with the delivery to determine whether the currents meet one or more predetermined criteria. The signal generator may also generate and deliver voltage pulses to the ablation device in the form of a pulse waveform after determining that the currents meet the one or more predetermined criteria.
