Abstract
The present disclosure provides catheter systems, electrode assemblies, and methods for electrically stimulating one or more points about the circumference of the renal artery to provide real time intraprocedural operational feedback to the operator of a renal denervation procedure to allow for more precise and thorough ablation of the renal artery and better patient outcomes. In many embodiments, an electrode assembly is provided that includes multiple splines that extend from an insulated proximal hub to an insulated distal hub and are interconnected to an electrical wire to allow the splines to independently function as electrical stimulation electrodes. The electrically active splines can then be energized at one or more desired points during a renal denervation procedure to provide operational feedback.
