摘要：
Embodiments are directed to radiopaque implantable structures (e.g., stents) formed of cobalt-based alloys that comprise cobalt, chromium, tungsten, and nickel. Tungsten is present above its solubility limit (about 15%), but is still only present as a super-saturated, primarily single-phase material exhibiting an FCC microcrystalline structure.
