Claim 0:
1. A method of ablating a greater splanchnic nerve to treat a patient diagnosed with heart failure, comprising:
positioning an endovascular catheter comprising a proximal region, a flexible shaft, and a distal region, wherein the flexible shaft connects the proximal and distal regions and has a length adapted and sufficient to access an azygos vein space of a T9, T10, or T11 thoracic vertebra of the patient relative to an access location when the proximal region remains external to the patient, the distal region comprising one or more ablation elements;
advancing the distal region through an azygos vein;
advancing the distal region from the azygos vein at least partially into a T9, T10, or T11 intercostal vein;

activating the one or more ablation elements;
delivering ablative energy to the greater splanchnic nerve using the one or more ablation elements while the distal region is at least partially in the T9, T10, or T11 intercostal vein; and

removing the endovascular catheter from the patient.
