A branched graft method includes securing a first end of a branch graft into a first conduit and subsequently moving the second end into a second conduit. The first conduit may be a branch vessel, such as a renal artery and the second conduit may be a main graft that extends over an aortic aneurysm. The branch graft may be deployed starting at an offset distance from the first end, thereby preventing the deployed portion from insertion into the first conduit and predetermining the insertion length into the target vessel. The first end may then be deployed to secure the first end to the first conduit. A branch graft may be a self-expanding stent graft having one or more ripcords, and/or a serpentine ripcord that enables non-linear deployment of the branch graft, or deployment that does not progress from one end to the opposing end.
