Abstract

A bifurcated stent comprises a trunk region (22) and at least one branch (24). The trunk region has a balloon expandable section (30) and a self-expandable section (28). The balloon expandable section is less compressible than the self-expandable section. The branch is self-expandable and extends from the self-expandable section of the trunk region. The balloon expandable section is less compressible than the branch.
