what are drug eluting stents made of?
16072
Drug-eluting stents have a polymer coating over mesh that emits a drug over time to help keep the blockage from coming back. In general, drug-eluting stents are preferred over bare-metal stents for most people. Drug-eluting stents are more likely to keep the blockage from recurring compared to bare metal stents.

Why haven't you switched to biodegradable? Cigarette filters are made of plastic. They're a synthetic fibre called Cellulose Acetate and take well over a decade to break down. Paper-based, biodegradable filters are now available, but very few have made the switch.

One estimate is that pads are made of up to 90% plastic – another is that a pack of menstrual pads is equivalent to 4 plastic bags . Tampons have plastic in them too – even in the string – and plastic applicators are made from polyethylene (PE) and polypropylene (PP).

Most coronary and peripheral vascular stents that have been tested have been labeled as “MR safe”; the remainder have been labeled as “MR conditional.”1 Tested coronary artery stents (including tested drug-eluting coronary stents) that are nonferromagnetic (all currently used coronary stents) can be safely scanned at 3 ...

Though stents are used to treat coronary artery disease (CAD) and its complications, including clots, stents themselves can also lead to clots. The presence of a foreign body, such as a stent, in constant contact with the blood may lead to clotting in some people.

Cards are made of several layers of plastic laminated together. The core is commonly made from a plastic resin known as polyvinyl chloride acetate (PVCA). This resin is mixed with opacifying materials, dyes, and plasticizers to give it the proper appearance and consistency.

Most OEM plugs, for example, are made with high purity platinum-iridium alloy coated tips, nickel-coated threads for corrosion resistance, and strong ceramic insulators. Aftermarket plugs often a lesser grade iridium platinum alloy (or even just platinum), which reduces the lifespan of the plugs.

A stent is a small, metal mesh tube that acts as a scaffold to provide support inside the coronary artery. A balloon catheter, placed over a guide wire, is used to insert the stent into the narrowed artery. Once in place, the balloon is inflated and the stent expands to the size of the artery and holds it open.
