Some articles on covered stent, covered:
... pseudoaneurysm communicates with an artery through a hole in the arterial wall, a covered stent may be placed endovascularly across this hole to "exclude it," or to prevent it ... The covered stent is composed of metal and is covered with polytetrafluoroethylene (PTFE) or another sterile fabric-like material ... The covered stent remains in place permanently, and the pseudoaneurysm, without a continuous flow of arterial blood, then thromboses ...
Famous quotes containing the word covered:
“The knowledge of an unlearned man is living and luxuriant like a forest, but covered with mosses and lichens and for the most part inaccessible and going to waste; the knowledge of the man of science is like timber collected in yards for public works, which still supports a green sprout here and there, but even this is liable to dry rot.”
—Henry David Thoreau (18171862)
