Abstract
Apparatus and methods are provided for flaring a stent deployed within a branch vessel including an ostium communicating with a main vessel, a first end of the stent extending at least partially from the branch. A catheter is provided that includes a balloon having a reinforced region adjacent an unreinforced region. When the balloon is positioned at a desired location, e.g., within a stent, prosthetic valve, or other tubular prosthesis, the balloon may be inflated to a first pressure causing the reinforced and unreinforced regions to expand substantially simultaneously. Upon inflation of the balloon beyond the first pressure, the reinforced region of the balloon remains at the first diameter and the unreinforced region continues to expand, e.g., to flare one or more ends of the prosthesis.
