Radiopaque enhanced nickel alloy for stents |
| 摘要 |
A stent includes a nickel-based alloy that includes 10-35 weight % metal member selected from the group consisting of platinum (Pt), gold (Au), iridium (Ir), osmium (Os), rhenium (Re), palladium (Pd), tantalum (Ta), and combinations thereof; 0-6 weight % cobalt (Co); 17-24 weight % chromium (Cr); 13-15 weight % tungsten (W); 0-3 weight % molybdenum (Mo); 0-5 weight % iron (Fe); and balance nickel (Ni). The nickel-based alloy may be a thin outer shell of a hollow stent. The nickel-based alloy may be used to form at least one of an inner core and an outer shell of a core-shell structure of a stent. |
