Abstract:
1. A method for installing a stent graft having an elongate limb and a truncate limb for treatment of an abdominal aortic aneurysm, comprising the steps of: puncturing a first common iliac artery and advancing a main body of the stent graft over a main body guide wire and a first introducer sheath to deliver and deploy said main body in therapeutic relation to said aneurysm; providing a main catheter having a lumen and an exit opening, where said lumen slideably receives an inner cannula, wherein said inner cannula includes a first cannula and a second cannula that are secured to one another at their respective distal ends, said second cannula has an extended arm, said extended arm secured to a distal end of said first cannula and unsecured to said first cannula proximal to said distal end a ferromagnetic material is mounted to a free end of said extended arm, said first cannula is adapted to slideably receive said main body guide wire; advancing said main catheter over said main body guide wire and said first introducer sheath in a proximal-to-distal direction until a distal, leading end of said main catheter is positioned distal to a distal end of said stent graft; and manually pulling said inner cannula in a distal-to-proximal direction to cause the extended arm to exit the exit opening formed in said main catheter.
