摘要：
Methods, apparatuses, and systems are described for minimizing various leakageeffects of multi-zone ablation devices. Apparatuses may include an ablationdevice for treatment oftissue including an ablation structure with a plurality of bipolar electrodezones. Each of the zonesmay include an in-zone channel pair comprising a positive channel and anegative channel. Theablation structure may be configured such that, for any adjacent electrodezone pair comprising afirst electrode zone and a second electrode zone adjacent to the firstelectrode zone, the positivechannel of the first electrode zone is electrically distinct from the positivechannel of the secondelectrode zone, and the negative channel of the first electrode zone iselectrically distinct from thenegative channel of the second electrode zone. Moreover, the ablationstructure may be arrangedsuch that a total number of electrically distinct channels that is less thantwice a total number of theplurality of electrode zones.
