Abstract
An irreversible electroporation and radio frequency ablation (IRE/RFA) generator includes an IRE pulse generator, harmonic filtration circuitry, and a waveform interleaver. The IRE pulse generator is configured to generate biphasic IRE pulses. The harmonic filtration circuitry is configured to convert the IRE pulses into an RF signal. The waveform interleaver, which is configured to receive the IRE pulses and the RF signal and generate an output signal having a composition of the adapted IRE pulses having a final shape and repetition rate, the converted RF sinusoidal signal, or a combined IRE/RFA output signal, by switching between the received IRE square pulses and the received converted RF sinusoidal signal.
