Abstract
A guide wire for intravascular investigations includes an elongated element, and electrical conductors extending along a length of the guide wire. A portion of one of the electrical conductors is provided as a layer of electrically conductive material, extending concentrically over the circumference of, and along the elongated element forming a part of the guide wire.
A method of manufacturing a conductor element for a guide wire with conductors in the form of a layer of a conductive material extending along the length of the conductor element is provided. A core element is provided. Overlapping layers of alternating insulating and conductive materials are applied concentrically around the circumference of the core element along a portion of its length, until a desired number of conductive layers have been applied.
