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