More Information
Summary:An intraluminal microneurography probe has a probe body configured to be introduced into an artery near an organ of a body without preventing the flow of blood through the artery. An expandable sense electrode and an expandable stimulation electrode are fixed to the probe body at one end of each electrode such that movement of the other end toward the fixed end causes the sense electrode to expand from the probe body toward a wall of the artery. A ground electrode is configured to couple to the body, and a plurality of electrical connections are operable to electrically couple the electrodes to electrical circuitry. The sense electrode is operable to measure sympathetic nerve activity in response to excitation of the stimulation electrode. A radio frequency ablation element is located between the expandable sense electrode and expandable stimulation electrode, and is operable to ablate nerves proximate to the artery.
