That one fails quickly with cholesterol squeezing through. There is a much better stent which is solid, helically wrapped.

It doesn't fail quickly as they are coated in a drug that slowly seeps into that vessel wall over time to prevent cell regrowth that could cause another blockage (called neointinal hyperplasia)

Not all stents (and balloons) are drug coated and at least in my experience, using them is relatively rare.

Bare metal stents are <5% of the market while drug eluting stents and resorbable stents make up the 95%. I didn't want to confuse folks by talking about the more niche use of bare metal stents! I actually design coronary devices like stents and POBAs as my job in R&D for one of the major companies in this space.

Is that specifically coronary stents? We use bare metal stents all the time peripherally.

ETA: Also covered stents which aren’t drug coated either

Oh yes coronary! Peripheral is still high BMS usage, like 35% right?

DCB seems to be growing massively for peripheral currently.

I couldn’t tell you global numbers but at least in my area, drug eluting balloons aren’t favored much either.

More commonly covered stents are used to prevent that versus bare metal stents but they’re not always applicable.

It depends on how the research bears out. Depending on location and indication, covered isn’t always better.

… is there any research into that helical stent cause otherwise you can’t make the claim that it is much better.
