摘要：
A reconfigurable delivery system is disclosed having a multi-lumen delivery catheter configuration that permits the delivery and staged release of a self-expanding main vessel stent-graft and a delivery sheath configuration that permits the introduction of various medical devices for the delivery and implantation of various branch vessel stent-grafts that are to be mated with the main vessel stent-graft. A method is disclosed wherein the delivery system is first used in the multi-lumen delivery catheter configuration to deliver and release a main vessel stent-graft that is configured for placement in the abdominal aorta for treatment of short-neck infrarenal, juxtarenal, and/or suprarenal aneurysms and then used in the delivery sheath configuration to facilitate the delivery of branch vessel stent-grafts that are configured to extend from the main vessel stent-graft into a respective renal artery.
