11. A method for stenting a branch artery, the method comprising the steps of:
-
providing a stent having a proximal end, a locus of points at the proximal end defining a surface, the surface being beveled with respect to a central axis of the stent, the proximal end comprising a beveled end;
inserting the stent into the branch artery, the beveled end being located at a mouth of the branch artery; and
orienting the beveled end, the surface being substantially aligned with the surface of a main artery in a vicinity of the mouth of the branch artery.
