A stent graft introducer has a nose cone dilator ( 8 ) and a distally opening capsule ( 18 ) on the nose cone dilator, a balloon guide ( 2, 30 ) extending into the capsule and affixed therein. Upon completion of deployment of a stent graft, a balloon catheter ( 96 ) including an inflatable balloon ( 98 ) thereon can be advanced over the balloon guide at least partially into the nose cone whereby the balloon can be inflated therein to provide a smooth transition from the nose cone to a delivery sheath ( 10 ) for retraction of the nose cone dilator through the deployed stent graft. The balloon guide can be a separate wire ( 30 ).
