13. A method of ablating a greater splanchnic nerve to treat a patient diagnosed with heart failure, comprising:
advancing a guidewire through an azygos vein and into a T9, T10, or T11 intercostal vein;
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 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 over the guidewire, through the azygos vein into the azygos vein space of the T9, T10, or T11 thoracic vertebra;
activating the one or more ablation elements;
delivering ablative energy to the greater splanchnic nerve using the one or more ablation elements; and
removing the endovascular catheter from the patient.
