Abstract:
1. A balloon expandable stent comprising: a main body having a plurality of radially expandable circumferential rings; a single flaring portion disposed on one side only of the main body and including at least a distal wing and a proximal wing, wherein each wing has a base and sides and is adapted to flare radially into a side branch; a U-shaped connector disposed between the main body and each wing, wherein the connector includes two legs and a cross-member where the legs are attached within one of the circumferential rings of the main body and the cross-member is attached to the base of one of the wings, the legs of said connector opening circumferentially where attached to the circumferential rings in response to expansion of the circumferential rings of the main body to cause the cross member to deform to cause the wing to flare radially; and struts extending from each side of the distal wing and the proximal wing to the main body, wherein the struts open with the distal wing and the proximal wing to provide coverage of a side branch ostium when each wing is opened into said ostium.
