Abstract
Devices, systems, and methods of the present disclosure are directed to selectively controlling delivery of electrical energy to an ablation electrode, with the selective control based on a history of the electrical energy delivered to a return electrode (e.g., electrical energy delivered in a current time-step and in one or more time-steps preceding the current time-step). Controlling electrical energy delivered to an ablation electrode based on the history of electrical energy delivered to a return electrode can reduce the likelihood of unintended tissue damage away from a treatment site as electrical energy is delivered to the treatment site via the ablation electrode. Further, or instead, the devices, systems, and methods of the present disclosure can reduce the likelihood of unintended tissue damage away from the treatment site while reducing or eliminating the need to interrupt lesion formation by the ablation electrode.
