Nitinol's medical applications owe their thanks to two milestone medical devices developed in the 1980s: Mitek's Homer Mammalok for breast tumor localization, and Nitinol Medical Technologies Inc.'s Simon nitinol filter, designed to trap blood clots in the venous system.
The Simon Nitinol filter was FDA approved in 1970 and is made of a thermal memory alloy, which makes it pliable at room temperature prior to insertion and rigid at body temperature once in the cava.
The SpideRX Device features a unique nitinol filter to capture embolic debris.
