Abstract
A tubular stent that uniformly scaffolds vessel tissue within a region that significantly changes diameter or transverse dimension. The invention may be practiced in lumens that taper in either retrograde or antegrade directions, and the transverse dimensional change may be relatively linear or flared. A catheter for delivering the stent of the invention may include a balloon having a comparably flared shape and an inverse conical distal end. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b)

11. A method of implanting a stent comprising:
-
providing a tubular stent having a length, distal and proximal ends and being mounted, in a compressed configuration, about a balloon inflatably disposed at a distal end of a delivery catheter, the compressed configuration having a generally constant diameter and a pattern density that declines over the length of the stent;
using the delivery catheter to transport the stent to a flared location in a vessel of a patient; and
inflating the balloon to deform the stent into an expanded configuration imbedded in the vessel, the expanded configuration having a flared shape and a pattern density that is generally uniform over the length of the stent. - View Dependent Claims (12, 13, 14, 15)
