Patent ID: 8197536

Claim:
A method for placing at least two separate and detached devices in a vessel bifurcation comprising the steps of: advancing a first wire into a main vessel past the vessel bifurcation and into a main branch of the vessel bifurcation; advancing a system over the first wire that passes through a first lumen of the system to a point proximal to the vessel bifurcation, wherein the system has at least two separate and detached expansion members at its distal end with the at last two separate and detached devices mounted thereon such that at least one of the at least two devices is mounted on each of the at least two separate expansion members, each of the at least two expansion members having a distal tip, said tips being held together by a connector; inducing a preferential bend along the system, the preferential bend having a predetermined fixed curved shape and being configured to automatically and freely rotate the system about the first wire relative to the vessel bifurcation to orient the system in a desired position; once the system is advanced to the point proximal to the vessel bifurcation, advancing a second wire through a second lumen of the system into a side branch of the vessel bifurcation without first withdrawing the second wire through the second lumen; advancing the system into the bifurcation along the first and second wires whereby the connector is released and the expansion members are advanced in parallel; simultaneously positioning one of the at least two devices in the main vessel and the main branch of the vessel bifurcation, and the second of the at least two devices in the side branch vessel of the vessel bifurcation; inflating the expansion members such that the devices are expanded to fill substantially the inner diameter of the main vessel and the side branch and main branch of the bifurcation; deflating the expansion members; withdrawing the second wire into the second lumen; and removing the system along the first wire leaving the devices emplaced at the vessel bifurcation.
