An access system is provided comprising a main tubular member having one or more lateral openings and a branch segment or secondary tubular member configured to be disposed through the lateral openings. The main tubular member is positioned in a vessel so that the openings are aligned with branches of the vessel. A secondary tubular member, or one or more branch segments, are then extended through the openings and into the branches to provide access for the delivery of therapeutic devices. Methods of deploying the access system to treat bifurcated or multi-branched vessels are also provided. |
