Abstract

A bifurcated stent includes a first stent section and a second stent section. The first stent section is balloon expandable, has an unexpanded configuration, an expanded configuration, and a tubular wall defining a secondary opening. The secondary stent section is self-expanding and an end of the secondary stent section is engaged to a portion of the tubular wall of the primary stent section defining the secondary opening. The secondary stent section has an unexpanded configuration with a first length and an expanded configuration with a second length where the first length is less than the second length. The secondary stent section is expanded to the expanded configuration after the primary stent section is expanded to the expanded configuration. The secondary stent section forms a portion of the tubular wall of the primary stent section in the unexpanded configuration.
