A stent system for placement in a bifurcated vessel includes a side branch stent. The side branch stent includes an expandable metallic distal section and a proximal section. The distal end of the proximal section is coupled to the distal section. The proximal section is made from a flexible material in the form of a sheet and is not supported by a frame proximally of the distal end. The proximal section includes a curled or tabbed proximal end adapted to engage walls of the main vessel at a junction of the main vessel and the side branch vessel. A second stent is configured for placement in the main vessel and the main vessel branch. Expansion of the second stent pushes the curled or tabbed proximal end of the first stent against the walls of the main vessel at the junction. |
