Abstract:
Systems, devices, and methods for transvascular ablation of target tissue. The devices and methods may, in some examples, be used for splanchnic nerve ablation to increase splanchnic venous blood capacitance to treat at least one of heart failure and hypertension. For example, the devices disclosed herein may be advanced endovascularly to a target vessel in the region of a thoracic splanchnic nerve (TSN), such as a greater splanchnic nerve (GSN) or a TSN nerve root. Also disclosed are method of treating heart failure, such as HFpEF, by endovascularly ablating a thoracic splanchnic nerve to increase venous capacitance and reduce pulmonary blood pressure.

Claim (Index 1):
A method of ablating a great splanchnic nerve or a greater splanchnic nerve root to increase splanchnic venous blood capacitance, comprising:\n advancing an elongate medical device into an azygous vein, the elongate medical device including a distal region, a flexible shaft with a fluid lumen therein, and an ablation element disposed at the distal region, the ablation element comprising a membrane in fluid communication with the fluid lumen, the ablation element at least partially defining a fluid chamber, advancing the ablation element from the azygous vein into a T9, T10, or T11 intercostal vein; when the ablation element is disposed in the intercostal vein, delivering a fluid through the fluid lumen and into the fluid chamber to expand the membrane into an expanded configuration that has a cylindrically shaped active ablation region, the active ablation region having a length from 5 mm to 20 mm and an outer diameter from 2 mm to 4 mm; and delivering ablation energy from the ablation member to create a continuous circumferential lesion having a length in a range of 5 to 20 mm, and thereby ablate a portion of a thoracic splanchnic nerve or a thoracic splanchnic nerve root.
