7. A catheter comprising:
an elongate shaft having a proximal end and a distal end and defining an axis that extends along a y-direction, wherein the y-direction is perpendicular to an x-direction, and wherein a z-direction is perpendicular to both the x-direction and the y-direction; and
a loop subassembly coupled to the distal end of the elongate shaft, the loop subassembly comprising:
a loop coupled at a distal portion of the loop to the distal end of the elongate shaft, wherein, in a neutral position, the loop defines a loop plane which is parallel to the axis of the elongate shaft, wherein the loop plane is an x-y plane extending in both the x-direction and the y-direction, wherein the loop plane is positioned in a different plane than the elongate shaft and is spaced from the elongate shaft along the z-direction, and wherein the loop is selectively deflectable, while maintaining a fixed radius of the loop, within the x-y plane that is the loop plane using at least one pull wire extending through the elongate shaft; and
a plurality of electrodes disposed on the loop.
