1. An apparatus, comprising:
an intravascular guide wire sized and shaped to be inserted into a blood vessel of a patient, the intravascular guide wire comprising:
a sensing element configured to measure a characteristic associated with the blood vessel while positioned inside the blood vessel; and
a cross-section comprising:
an outer perimeter of an electrical conductor coupled to the sensing element;
an inner perimeter of an insulating layer and an outer perimeter of the insulating layer; and
an inner perimeter of a core wire and an outer perimeter of the core wire,
wherein the outer perimeter of the core wire comprises a closed shape,
wherein the inner perimeter of the insulating layer is in contact with the outer perimeter of the electrical conductor and the inner perimeter of the core wire is in contact with the outer perimeter of the insulating layer such that the cross-section is solid within the closed shape of the outer perimeter of the core wire.
