Title:
DEVICES, SYSTEMS, AND METHODS FOR TREATMENT OF HEART FAILURE BY SPLANCHNIC NERVE ABLATION
Document Type and Number:
WIPO Patent Application WO/2018/023132
Kind Code:
A8
Abstract:
Apparatuses and methods for treating a heart failure patient by ablating a nerve of the thoracic splanchnic sympathetic nervous system to increase venous capacitance and reduce pulmonary blood pressure. A method comprising: inserting a catheter into a vein adjacent the nerve, applying stimulation energy and observing hemodynamic effects, applying ablation energy and observing hemodynamic effects, applying stimulation energy after the ablation and observing hemodynamic effects and monitoring for presence of the lung in the ablation zone. An alternative method comprising: inserting a catheter into a vein adjacent the nerve, detecting that lung tissue is a safe distance from an ablation zone, and delivering ablation energy to the target nerve when lung tissue is a safe distance from the ablation zone.
