An ostial stent is operable to be placed at the ostium of a patient's vascular system so as to improve vessel patency in the ostial region. The ostial stent includes a stent tube that presents spaced apart proximal and distal stent openings and a longitudinal stent passage that extends between the openings. The stent tube includes a selectively-expandable tube section and a self-expandable tube section. The self-expandable tube section projects longitudinally from one of the stent openings, and is automatically expandable to a flared condition for placement within the ostium. |
