July 17th :Types of Stents
A stent is a mesh-wire tube placed inside a passageway in the body to prevent that path from constricting or closing off. While the most known placement is in coronary arteries, stents can be put in to improve flow to various organs and even to prop open the esophagus. The most basic stent is simply metal, although newer stents are features such as releasing the anticoagulants the patient normally has to take directly into the blood.
There are three major types of stents:
BMSs (Bare metal stents)
DESs (Drug-eluting stents)
and “Covered stents”
Out of these three types, I would recommend the DES. While the covered stent prevents tissue from growing through the meshing (This type of stent has a layer of non-toxic metal alloy surrounding it) and allows blood flow to resume at a pretty normal rate, it is bulkier, harder to place, and is not able to fit into more restricted areas. If I needed stents, I would go with the drug-releasing smaller stent; it just seems easier to incorporate despite the promising potential of the covered stent.

good opinion
I like how you observed that there are other organs that a stent can be placed in. I agree too- I would pick the DES. Good job.
i was jsut wondering what the pros were for the other stents.i mean they must be good for some reason or another. otherwise i would probably go with the DES as well
