Ultra-Thin Strut Technology (<60 $\mu$m)
In 2026, the mantra for stent design is "thinner is better." Cobalt-chromium and platinum-chromium alloys have allowed for the mass production of Ultra-Thin Strut stents (e.g., Orsiro, Supraflex Cruz). These struts are thinner than a human hair (approximately $60$ $\mu$m).
Thinner struts cause less "turbulence" in blood flow and less mechanical injury to the vessel wall during deployment. Clinical registries in 2026, such as INFINITY-SWEDEHEART, show that these ultra-thin designs have the lowest rates of Target Lesion Failure (TLF) in history, particularly in small vessels and diabetic patients where traditional, thicker stents often failed.
