At least one coil may be formed around a distal portion of the elongated body from a plurality of helical wraps of a continuous wire that extends to the proximal end of the elongated body through the lumen. One or more coils may be provided and each may be configured to function as either a ring electrode or a location sensor.00 iio ("IN36 12 40 FIG. 4 34 36 124 40 FIG. 5
