Abstract: A neuromodulation catheter is positionable in a blood vessel having a wall for use in delivering therapeutic energy to targets external to the blood vessel. An electrically insulative substrate such as an elongate finger is carried at a distal end of the catheter body. The substrate has a first face carrying a plurality of electrodes, and a second face on an opposite side of the substrate from the first face. The finger is biased such that when expanded within the blood vessel, it forms a spiral configuration with the first face facing outwardly to bias the electrodes in contact with the blood vessel wall.
