1. A method of ablating a greater splanchnic nerve or a greater splanchnic nerve root to increase splanchnic venous blood capacitance, comprising:
advancing an elongate medical device into an azygos vein, the elongate medical device including a distal region and an ablation element disposed at the distal region;
advancing the ablation element from the azygos vein into a T9, T10, or T11 intercostal vein;
when the ablation element is disposed in the T9, T10, or T11 intercostal vein, delivering energy from the ablation element; and
creating a lesion having a length in a range of 5 to 20 mm,
whereby creating the lesion ablates a portion of the greater splanchnic nerve or the greater splanchnic nerve root.
