Fort Wayne Metals has developed a composite wire technology with integrated proximal-to-tip guidewire performance in mind. One critical area in medical device practice is in vascular access guidewires. Many workhorse guidewires, 0.3302 mm to 0.3556 mm [0.013 in to 0.014 in], use a stiff material body (often stainless steel or CoNiCr) for control and a superelastic Nitinol tip for flexible navigation. The combination of properties for these hybrid wires is often used for effective navigation to areas of the heart, brain, and vessels of appendages.
