1. A catheter, comprising:
an elongated shaft, wherein the elongated shaft includes a proximal portion and a distal portion, a flexible planarity member disposed within the elongate shaft, wherein the flexible planarity member defines a longitudinal cutout; a positioning sensor comprising a unitary piece of wire that includes a first conductive wire segment, a second conductive wire segment, and a third conductive wire segment, wherein:
the first conductive wire segment is wound around a longitudinal axis, forming a wound coil disposed in the distal portion of the elongated shaft, wherein the wound coil is disposed within the longitudinal cutout of the flexible planarity member and the flexible planarity member provides for unidirectional bending of the elongate shaft;
the second conductive wire segment extends from a first coil end of the first wire segment and through the proximal portion of the elongated shaft; and
the third conductive wire segment extends from the second coil end of the first wire segment and through the proximal portion.
