Flexible tissue ablation elements for making long lesions
 Devices and methods for ablating body tissue use wire wound about a support body in adjacent windings to form one or more elongated electrodes. A connection couples the wire to a source of ablation energy for transmission by the elongated electrode to ablate tissue. The adjacent windings are spaced apart to impart enhanced flexibility to the elongated electrode during use.
