Abstract
High-frequency irreversible electroporation (H-FIRE) is a tissue ablation modality employing bursts of electrical pulses in a positive phase-interphase delay-negative phase-interpulse delay pattern. Despite accumulating evidence suggesting the significance of these delays, their effects on therapeutic outcomes from clinically-relevant H-FIRE waveforms have not been studied extensively. The present invention provides methods of pulse delivery, including delays, that mitigate bubble formation and/or minimize the risk of arcing, such as due to the presence of bubbles, and/or minimize muscle stimulation are described herein.
