Isn't silicone more human-friendly than metal?
So, since I myself probably have atherosclerotic (plaque) causing peripheral arterial disease...
(here's a demo: http://www.youtube.com/watch?v=UhwX5zO17qk

i got to thinking:

  • on the one hand, there's the metal scaffolding, which seems like it might be painful.
  • on the other hand, there's these floppy balloons of angioplasty, which are then removed.

So there's no such thing as firm, silicone scaffold-stents, such as the silicone of spatula's?

For a stent to be inserted into an artery or a vein, it must be expandable. There are self expanding stents and balloon expandable stents. The stent is inserted through the vasculature via a catheter in a contracted state and then expanded at the site of stenosis. I'm not sure if a silicone stent could meet these requirements. It's a good question for Dr. Sclafani. Moreover, I believe that you would still have the problem of having a foreign object in the vein or artery which would increase the likelyhood of clots.

OK, probably silicone isn't feasible.
I wonder why they can't do laser for atherosclerosis causing Peripheral Artherial Disease
...just like they do laser for kidney stones? See:

I know they do laser for varicose veins, but I think it's just for cosmetic reasons, whereas I have excruciating pain in veins on upper part of foot, and in arch (as in tarsal tunnel syndrome.
