Devices and methods are described to facilitate the coupling of two wires introduced into the vascular system at two different points in the body. The coupling enables the formation of a continuous wire entering the body at one point and exiting at another remote point. The device consists of two wires 'A' and 'B' with a magnetic element attached to one end of each wire. The coupling is formed by the forces of attraction between the magnetic elements. Wire 'A' is introduced at one point in the vascular system, for example, in the femoral artery. Wire 'B' is then introduced at another point in the vascular system, for example, the axiliary artery. The wires are advanced towards each other under fluoroscopic guidance. The magnetic tips couple once the two wires near each other. The coupled wires are then withdrawn together from either of the two access sites. Once the magnetic coupling exits the body, a single wire is left traversing the vascular system. This wire can then serve as a monorail over which to exchange catheters, transport tools and implants and to perform procedures. This device will facilitate the development of bi-directional endovascular, biliary, genito-urinary and gastro-intestinal procedures. The applications of this device are not limited to human subjects.
