Hlau stents yog pas nrig- cov qauv kev txhawb nqa ua los ntawm cov khoom siv hlau, xws li npib tsib xee-titanium alloys, stainless hlau, thiab magnesium alloys, thiab tau dav siv hauv kev kho mob, khoom siv sab nraum zoov, thiab kev lag luam. Hauv kev kho mob, lawv suav nrog vascular stents, cardiac stents, esophageal stents, thiab orthopedic implants. Piv txwv li, npib tsib xee-cobalt-chromium-molybdenum alloy ureteral stents tuaj yeem tso rau hauv qhov chaw ntev dua 12 lub hlis, thaum biodegradable magnesium alloy stents muab kev txhawb nqa thiab biodegradability. Hlau stents rau cov tsev pheeb suab sab nraum zoov yuav tsum muaj av thiab yuav tsum muaj kev nyab xeeb nyob deb.
Thaum ntxov, cov qauv no feem ntau siv cov khoom siv hlau, tab sis tau maj mam hloov mus rau hauv cov khoom siv biodegradable. Hlau-raws li thiab magnesium alloy stents ua tiav cov qauv pore optimized, thaum txheej Fe-Zn alloys txhim kho tus nqi degradation thiab txhua yam khoom. Kev lag luam thoob ntiaj teb loj rau bioresorbable cardiovascular stents yog npaj kom ncav cuag US $ 1690 lab los ntawm 2030, nrog Suav chaw tsim tshuaj paus Lifetech Scientific ua ib lub ntiaj teb cov neeg tsim khoom loj. Nickel-titanium alloy stents ua lag luam nyob rau hauv txoj hlab pas vim yog lawv cov superelasticity thiab cov duab cim xeeb.
