STENT DELIVERY AT A BIFURCATION, SYSTEMS AND METHODS

摘要

The present invention provides systems and methods for delivery of a stent or scaffold at a blood vessel or body lumen bifurcation. A method can include positioning a scaffold at a bifurcation of a main lumen into first and second branch lumens using a first expansion catheter, inflating a main balloon of the catheter to expand the proximal portion of the scaffold, positioning a second expansion system, and expanding the distal portion of the scaffold on a generally distal side of the bifurcation.
