A nitinol medical stent is a small, mesh-like tube made from nitinol, a metal alloy of nickel and titanium known for its shape memory and superelasticity. These unique properties make nitinol especially useful in medical applications where flexibility, durability, and precise deployment are crucial.

The success rate of surgeries involving stents—particularly in cardiovascular procedures like coronary artery stenting—is generally high, with significant improvements in patient outcomes. However, the exact success rate can vary depending on several factors, including the type of stent used, the co
