A guide wire (1) to assist percutaneous endovascular deployment which has zones of varying stiffness. An elongate central zone (3) of high stiffness, a proximal zone (4) of transition from high stiffness to semi-stiffness and a distal zone (5) of transition from high stiffness to being relatively flexible. The distal zone (5) has three zones, a semi stiff zone (11) adjacent the central zone, a transition zone (13) being of flexibility of from semi-stiff extending to flexible and a tip zone (15) being of high flexibility. The distal tip has a small J curve (16) to ensure that it is atraumatic in vessels and to prevent damage to the aortic heart valve. The distal zone (5) can also have a large curve to assist with anchoring the guide wire into the aortic arch.
