Abstract
A stent-graft assembly and method of preparing the same are disclosed. In a first embodiment, the assembly comprises a stent and a graft, wherein the graft has a delivery configuration and a treatment configuration in relation to the stent. In the delivery configuration, the graft material is longer than the stent, covers the outer diameter of the stent, and is folded under and into the inner diameter of the stent. In the treatment configuration, the graft is shorter in length than the stent, such that the graft is no longer folded under the ends and the end regions of the stent are uncovered. The graft is sufficiently affixed to the stent to prevent migration of the graft, yet sufficiently free of the stent such that it can assume a second configuration upon deployment of the device.
