1. A method of manufacturing a medical device for neuromodulation, the method comprising:

  • positioning a thermocouple assembly along a distal portion of a catheter, wherein the thermocouple assembly comprises a first wire and a second wire composed of dissimilar metals, and wherein the thermocouple assembly comprises a thermocouple junction at least proximate the distal portion;

    wherein the first wire has a plurality of exposed and insulated regions along a portion of the first wire proximate the distal portion, and the second wire of the thermocouple assembly remains insulated; and

    wherein the distal portion of the catheter includes an elongated tubular shaft configured to transform between a delivery configuration and a deployed configuration at a target treatment site within a blood vessel of a human patient, and wherein, in the deployed configuration, the exposed regions of the first wire define a plurality of energy delivery portions positioned to deliver energy to target tissue adjacent a wall of the blood vessel.
