Nitinol is a nickel-titanium alloy that returns to a set shape when warmed and is very springy, used in stents and guidewires.
Readiness: lab lab studies · prototype demonstrated objects · commercial products or buildings in real use · review summaries of other studies.
Duerig, Pelton, and Stöckel reviewed nitinol in stents, guidewires, and other medical devices.
Built / tested: stents, guidewires
