A stent delivery system comprises an inner member and an expandable balloon mounted thereon. The stent has a distal edge and a proximal edge, and at least a portion of the stent has an outer diameter that tapers down towards the distal edge. Each stent segment is comprised of a wire member bent to form a generally cylindrical mesh that includes a plurality of axial bends defining proximal and distal edges of the stent segment. The width and/or outer diameter of the axial bends defining the distal edge and/or the proximal edge may be reduced to provide a low profile. |
