Abstract
Official abstract text for this publication.
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).
First claim
Opening claim text (preview).
The invention claimed is: 1. A medical system comprising: a device comprising: a plurality of transducer element sets; an expandable frame comprising a proximal end and a distal end; and a plurality of flexible circuit strips, an elongated portion of each flexible circuit strip positioned on at least one surface portion of the expandable frame located between the proximal and the distal ends of the expandable frame, each flexible circuit strip having a respective length exten…
