SMA Biomedical Applications

Shape memory alloys (SMAs) are a group of metallic materials that exhibit unique properties and, accordingly, draw the interest of scientific communities and industries. The most used SMA in the biomedical field is Nitinol (NiTi). Nowadays, a large majority of SMA medical devices are produced using NiTi alloys, thanks to the material's good workability during the martensite phase, good resistance to corrosion and fatigue, U.S. Food and Drug Administration approval, and good compatibility with magnetic resonance imaging and computer tomography scanning.
