1. An ablation and mapping device for applying electrical energy, the device comprising:
an elongate body; and
an applicator region extending from a distal end region of the elongate body, the applicator region comprising:
a first wire electrode extending between a first arm and a second arm;
a second wire electrode extending between the first arm and the second arm, wherein the second wire electrode is substantially parallel to the first wire electrode;
a plurality of mapping electrodes on the first and second arms and on the elongate body;
wherein the applicator region is configured to deliver energy between the first wire electrode and the second wire electrode.
