Nitinol - Material with Unusual Properties

WebbNitinol (nickel-titanium alloy) is a shape-memory metal alloy that has been used in medical applications for years. Since Nitinol “self-fashions” with heat, the crimping maneuver is dramatically simplified. The SMart 360º Piston is a completely encircling piston containing heat-activated Nitinol. WebbThe stent is a laser cut self-expanding stent composed of a nickel titanium alloy (Nitinol). On both the proximal and distal ends of the stent, radiopaque markers made of tantalum increase visibility of the stent to aid in placement.
