Abstract
The present invention provides methods and devices for placement of a stent in a bifurcation or ostial lesion. The stent comprises a main body and a flaring portion. The main body is designed to expand and support a main vessel of the bifurcation and defines a main body axis. The flaring portion is disposed on a side of the main body and is adapted to flare radially and offset the main body axis in response to expansion of the main body. The flaring portion comprises at least one distal wing and at least one proximal wing. Each wing is aligned along the main body axis. The at least one proximal wing is longer than the at least one distal wing, providing greater coverage of the proximal side of the side vessel than on the distal surface of the side vessel.
