Abstract
A first catheter has a return bend formed near its distal free end and a first magnet is mounted on the distal free end. The first catheter is introduced through a sheath in a first common femoral artery into an elongate leg of a stent graft and pulled back until the return bend positions the first magnet near a truncate leg of the stent graft. A second catheter having a second magnet on its distal free end is introduced through a second common femoral artery and positioned near the first magnet so that the magnets become interconnected. The second catheter is pulled into the stent graft, a guide wire is inserted through it, and a second sheath is introduced into the stent graft. A contralateral limb is deployed through the second sheath and the second sheath is removed. In another embodiment, catheters with magnets pull a nephroureteral stent from a kidney.
