Abstract
A covered stent for treating a stenotic region in a blood vessel. The stent covering has different porosities in different regions. In those regions, typically the ends, where tissue ingrowth and re-endothelialization are desired, the stent covering is more porous, and in those regions were it is desirable to inhibit such ingrowth, the stent covering is substantially non-porous.
