Improvement on Stent

(4 Apr 2008)
I have an idea on improving the strent.
When I look at the procedure, the strent expand after it is inserted
into the correct portion of the block artery.
But I can imagine one problem is that the lining of the artery is over

stretch because the plaque is still there.
So, I proposed a tiny medicine bag at the front of the stent.
This medicine bag will contain a chemical that can be use to dissolve
the plaque on the artery. This chemical will be design so that it is
released slowly.
