Electrode apparatus for blocking or controlling nerves in body

Abstract

An electrode apparatus for nerve denervation or modulation in vivo includes: a main body including a shaft; and an electrode unit formed to protrude from one end of the shaft, configured to denervate or modulate at least a part of nerves on a tube in a body, and including a base layer and an electrode layer disposed on the base layer. The electrode unit includes: a first electrode disposed along a longitudinal direction of one side of the base layer; an electrode layer including a second electrode disposed along a longitudinal direction of the other side of the base layer; a current sensor unit formed in a region between the first electrode and the second electrode and configured to measure a current generated from the first electrode or the second electrode; a plurality of temperature sensor units spaced apart from each other at a predetermined interval between the first electrode and the second electrode and configured to measure a temperature; and a controller configured to calculate a resistance based on the current measured by the current sensor unit and calculate a diameter of the tube in the body based on the calculated resistance.
