/Application Of Non-therapeutic Waveforms With Gradient Sensing To Predict Pulsed Field Ablation (pfa) Fields
Abstract
A method and a pulsed electric field (PEF) ablation instrument are provided. According to one aspect, a method in a PFA generator includes receiving electrical responses for each of at least one non-therapeutic waveform. The process also includes determining an electric field distribution based at least in part on the received electrical responses. The process further includes selecting a non-therapeutic waveform that produces an electric field distribution that satisfies criteria. The process also includes mapping the selected non-therapeutic waveform to an ablative waveform.
