1. A partially-masked electrode for a catheter, comprising:
a conductive material; and
an insulated coating having an outer surface, wherein the insulated coating is applied locally as a ring having an outer perimeter and an inner perimeter, the inner perimeter and the outer perimeter are aligned such that center points of each of the inner perimeter and the outer perimeter are disposed on a plane parallel to a longitudinal axis of the catheter, the outer perimeter and the inner perimeter of the ring being disposed around an outer perimeter of the conductive material such that the inner perimeter of the ring of insulated coating projects above and over an outer edge of the conductive material to create an overhang of the insulated coating over the conductive material and defines an opening that exposes an area of the conductive material.
