It is uncommon for cardiac (coronary) stent to be made of nitinol. It is not necessary due to 316L and L605 alloy, which are more affordable than nitinol, being good enough to withstand the pulsatile strain in the coronary artery. Nitinol stent however is commonly used in areas with high strain or tortuous section like femoral artery, or if removal is desired like in IVC filter. Source: I work in the industry

Stephen Abracadabra beat me to it. Most of our coronary stents are cobalt alloy. We do however implant an aortic porcine tissue valve which has a reticulated Nitinol frame and is delivered transcatheter like a coronary stent. Slightly larger catheter though (16F)

@thebrainnugget

Depends on the size, how much it gets deformed, and the Nickle-Titanium ratio. However, as long as you stay within a certain stress percentage, there is little-to-no metal fatigue and it can return to its original shape for a very long time.

Nitinol caught my eye with its application in stents and has been fascinating me for a few weeks now. Brilliant to see a video come out about it right now!

ive heard about using nitinol in the "tires" for future vehicles like the mars rover where a tire inflated with a gas isnt an option and because its a "tire" it needs to retain its shape.

@TheDuckofDoom.

5 жыл бұрын

In the literal sense a thick iron hoop can be a tire, as seen on old horse drawn wagons. I'm not certain of the etymology but I think the term comes from the iron hoop "tying" the other wheel parts together similar to the hoops on a wooden cask, but of course it also served to wear much longer than bare wood and was fairly simple to replace. The moon rovers used woven spring-steel wire tires. Inflation with gas is always an option but repairing punctures and re-inflating could be a bit more trouble.
