Abstract
Systems and associated methods form larger and deeper lesion patterns by shaping a support body with multiple electrodes in ways that increase the density of the electrodes per given tissue area. The support body can carry either elongated, continuous electrodes or arrays of non-contiguous, segmented electrodes.
Claims11
A device for ablating body tissue comprising
- a support element having a curved region to peripherally contact a tissue area, and
- at least two energy emitting zones on the curved region mutually separated across the contacted tissue area, the mutual separation between the zones across the contacted tissue area creating, when the zones simultaneously emit energy, an additive heating effect to form a continuous lesion pattern in the contacted tissue area that spans across the contacted tissue area.
