1. An ablation catheter configured to ablate septal wall tissue, comprising:

  • an elongate delivery tube defining a major axis and having a distal end adapted for insertion into the heart of a patient;

    at least one resilient arm with a delivery configuration and an expanded configuration, wherein the at least one resilient arm comprises a distal arm section, a proximal arm section, and a bend section disposed between the distal arm section and the proximal arm section, the proximal arm section of the at least one resilient arm defining a shape selected from the group consisting of cordate, hastate, and sagittate when the at least one resilient arm is in the expanded configuration; and

    a plurality of electrodes disposed on the proximal arm section of the at least one resilient arm, wherein the distal arm section defines a substantially linear configuration substantially orthogonal to the major axis when the at least one resilient arm is in the expanded configuration.
