Shape Memory Alloys (SMA) is a special class of metals that have the ability to restore their original shape after severe deformation. SMAs find applications in various industries such as automotive, aerospace, robotics and biomedical. Nickel-Titanium alloy (nitinol) has been found to be the most useful shape memory alloy in biomedical applications such as tweezers for small incisions, cardiovascular stents, coroner angiography, tendon fixation tool and orthodontic wires. Some of the major properties of nitinol include high fatigue strength, nonmagnetic, high power/weight ratio, corrosion resistance, heat resistance, and biocompatible. The increased utilization of this alloy to manufacture various medical devices has changed the algorithm of disease treatment. With the growth in geriatric population globally and the increasing rate of vascular diseases such as peripheral arterial diseases and coronary artery diseases, the nitinol medical devices market shows tremendous growth potential, particularly in developing nations.
