Abstract
A stent graft system includes a first layer of graft material, a second layer of graft material, one or more stent members, one or more reducing belts, and a release wire. The one or more stent members are located between the first layer of graft material and the second layer of graft material. The second layer of graft material is formed to have a corresponding channel over each of the one or more stent members. The one or more reducing belts each include a loop at both ends and each is located in a corresponding channel around a corresponding one of the stent members. The release wire passes through both loops of each of the one or more reducing belts when the one or more stent members are in a compressed state. Pulling the release wire allows for the stent graft system to radially expand.
