An expandable stent to be positioned and implanted at the intersection of a great vessel and a branch vessel. A deployable stop engages the wall of the great vessel surrounding the ostium and the stent body extends into and is implanted in a branch vessel. A sheath holds the stent in a compressed state during delivery and a retainer holds the stop in an undeployed position while the delivery system is advanced to a desired location at the intersection of the great vessel and the branch vessel. |
