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: A device positionable in a cavity of a bodily organ (e.g., a heart) may discriminate between fluid (e.g., blood) and non-fluid tissue (e.g., wall of heart) to provide information or a mapping indicative of a position and/or orientation of the device in the cavity. Discrimination may be based on flow, or some other characteristic, for example electrical permittivity or force. The device may selectively ablate portions of the non-fluid tissue based on the information or mapping. The device may detect characteristics (e.g., electrical potentials) indicative of whether ablation was successful. The device may include a plurality of transducers, intravascularly guided in an unexpanded configuration and positioned proximate the non-fluid tissue in an expanded configuration. Expansion mechanism may include helical member(s) or inflatable member(s).
