Memory alloy advancement adds stiffness to the mix.
Using NiTiCo, a nickel-titanium-cobalt alloy, device makers could design smaller shape memory or superelastic devices such as stents and guidewires that retain their structural integrity under stress, but that enter the body through smaller access sites.
Shape-memory stents made of superelastic nitinol, a nickel-titanium alloy, can be compressed, fed through an artery and restored to their intended shape upon delivery to keep diseased arteries open to blood flow. And superelastic nitinol guidewires, unlike those made from stainless steel, can conform to tortuous vascular spaces without compromising their structure. Yet, despite its profound impact in some medical applications, the alloy remains too flexible for other medical applications…
