Abstract
The invention provides an expanded vascular stent having a non-circular cross-section. The expanded stent may have, for example, a 'D' shaped cross-section for collateral deployment within a common body lumen. A curved edge of the stent engages a body lumen while an alignment edge engages a collaterally deployed stent. A segment of graft material having at least one end cut on a bias may be attached to the stent so that the graft material extends substantially between the proximal and distal ends of the stent along its alignment edge, yet only partially along its curved edge to assist in forming a hemostatic seal. The apparatus may also be used for collaterally deploying stents within the common body lumen.
