Embodiments are directed to radiopaque implantable structures (e.g., stents) formed of cobalt-based alloys that comprise cobalt, chromium and one or more platinum group metals, refractory metals, precious metals, or combinations thereof. Platinum group metals include platinum, palladium, ruthenium, rhodium, osmium, and iridium. Refractory metals include zirconium, niobium, rhodium, molybdenum, hafnium, tantalum, tungsten, rhenium, and precious metals include silver and gold. In one embodiment, the one or more included platinum group or refractory metals substitute at least partially for nickel, such that the alloy exhibits reduced nickel content, or is substantially nickel free. The stents exhibit improved radiopacity as compared to similar alloys including greater amounts of nickel.

Systems, devices, and methods are provided that enable the sensing of an analyte level within, e.g., the dermal layer of the skin of a subject. These systems, devices, and methods can utilize modalities that increase perfusion in an area local to a dermal sensor.

The present disclosure is directed to tantalum-alloy products, implantable medical devices that incorporate tantalum-alloy products such as stents or other implantable medical devices, methods of making and/or processing the tantalum-alloy products and implantable medical devices, and methods of using the implantable medical devices. In an embodiment, a stent includes a stent body having a plurality of struts. At least a portion of the stent body is made from a tantalum alloy. The tantalum alloy includes a tantalum content of about 77 weight % ('wt %') to about 92 wt %, a niobium content of about 7 wt % to about 13 wt %, and a tungsten content of about 1 wt % to about 10 wt %. The tantalum alloy exhibits at least one mechanical property modified by heat treatment thereof, such as yield strength, ultimate tensile strength, or ductility.
