26. A method for increasing splanchnic venous capacitance in a patient, 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 is a length sufficient to access a T9, T10, or T11 intercostal vein of the patient relative to an access location when the proximal region remains external to the patient, the distal region comprising at least one ablation element;
advancing the distal region through an azygous vein;
advancing the distal region from the azygous vein and into the T9, T10, or T11 intercostal vein;
activating the at least one ablation element;
ablating a greater splanchnic nerve using energy generated with the at least one ablation element; and
removing the endovascular catheter from the patient.
