Abstract
To provide a catheter for mapping and ablation of epicardial tissue.SOLUTION: A catheter for mapping and ablation of epicardial tissue includes: a shaft configured for insertion into a body of a subject; a distal assembly configured at a distal end of the shaft, the distal assembly being expandable from a collapsed state to a deployed state and comprising at least two frame elements, each frame element comprising an arched distal portion on which a plurality of electrodes for delivery of ablation energy are disposed, wherein in the deployed state, the distal assembly assumes a concave profile for conforming to a curvature of the epicardium; and a plurality of position sensors disposed on one or both of the shaft and the frame elements for tracking a position and an orientation of at least a portion of the distal assembly or the shaft.SELECTED DRAWING: Figure 3A
