Abstract: Intra-cardiac voltage data display systems display a plurality of data sets derived at least from intra-cardiac voltage data sampled by an electrode. In some embodiments, at least some of the data sets are derived from a portion of the intra-cardiac voltage data that excludes an excludable portion of the intra-cardiac voltage data having a relationship with an occurrence of a particular cardiac event to facilitate identification of the existence of a transmural lesion in tissue adjacent the electrode. In some embodiments, the particular cardiac event is the occurrence of an R wave in the cardiac cycle, and the excludable portion is a V wave in the cardiac cycle.

Abstract: Transducer-based systems can be configured to display a graphical representation of a transducer-based device, the graphical representation including graphical elements corresponding to transducers of the transducer-based device, and also including between graphical elements respectively associated with a set of the transducers and respectively associated with a region of space between the transducers of the transducer-based device. Selection of graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Selection of a plurality of graphical elements and/or between graphical elements can cause visual display of a corresponding activation path in the graphical representation. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers.

Abstract: At least a first transducer set of a transducer-based device may be activated to deliver a first high voltage pulse set to cause pulsed field ablation of tissue. A data set may be monitored, the data set indicative of separation between a second transducer set of the transducer-based device and a tissue surface in a bodily cavity. Depending on a degree of separation, indicated by the data set, between the second transducer set and the tissue surface, a quality of a lesion producible in the tissue by the first high voltage pulse set may be determined. At least in response to the determination of the quality of the lesion producible in the tissue by the first high voltage pulse set, display of a graphical element set may be caused to indicate the determined quality of the lesion.

Abstract: A pulsed field ablation system may be configured to control characteristics of high voltage pulses delivered during one or more cardiac cycles based on a characteristic of one or more cardiac cycles. For example, if a particular cardiac cycle has a first characteristic, a first high voltage pulse train may be delivered, but if the particular cardiac cycle has a second characteristic different than the first characteristic, a second high voltage pulse train having at least a different characteristic than the first high voltage pulse may instead be delivered.
