Abstract: The present invention embodies delivery systems and methods of repairing vasculature. Various embodiments of bifurcated grafts and limb components can be delivered by delivery systems that provide enhanced control of self-expanding structure of a modular grafting system.

Abstract: Apparatus and surgical methods establish temporary suction attachment to a target site on the surface of a bodily organ for enhancing accurate placement of a surgical instrument maintained in alignment with the suction attachment. A suction port on the distal end of a supporting cannula provides suction attachment to facilitate accurate positioning of a needle for injection penetration of tissue at the target site on the moving surface of a beating heart. Force applied via the suction attachment to the surface of the heart promotes perpendicular orientation of the surface of the myocardium for enhanced accuracy of placement of a surgical instrument thereon. A hollow needle and a supporting channel therefor, each include a slot along an outer wall between ends thereof, are selectably rotatable to align the slots for releasing a cardiac lead from within the needle through the aligned slots.
