Abstract: A delivery system for a stent to a bifurcated region includes an elongated shaft with first and second branches extending from the elongated shaft. First and second branches have first and second balloons mounted thereon, respectively. A first guidewire extends the entire length of the delivery system and into the first branch for an “over-the-wire” configuration. A second guidewire extends into the second branch, but enters the elongated shaft near a distal end thereof for a “rapid-exchange” configuration. A guideway is formed in the elongated shaft and extends into the first guidewire lumen. The guideway may be forced open by a guide member slidably coupled to the elongated shaft, thereby adjusting the effective over-the-wire length of the first guidewire.

Abstract: A bifurcated catheter includes a first catheter branch having a first distal portion and a second catheter branch having a second distal portion. The first and second distal portions are linked together for delivery to the bifurcated region. Upon delivery to the bifurcated region, the first and second distal portions are released from each other such that the first and second catheter branches may be tracked into first and second vessel branches, respectively. The first and second distal portions can be linked together by inserted the second distal portion into a skive in the first distal portion, adhesive beat bonding the distal portions together, a coil wrapped around the distal portions, or a spiral cut in the first distal portion sized and shaped to received a guidewire.
