Abstract

A neuromodulation device includes an ablation valve with electrodes provided about its circumference. The valve dynamically reacts to fluid pressure within the vessel. When a pressure within and distal said ablation valve is greater than the body fluid pressure within the vessel, said ablation valve closes and the electrodes move out of contact with the endothelium of the vessel. When a pressure within and distal the ablation valve is less than the body fluid pressure upstream of the valve, the valve opens such that the electrodes are in circumferential contact with the endothelium. Fluid can be injected into the valve to alter the local pressure about the valve and force the electrodes into contact with the endothelium.
