An improved medical device reduces the loss of longitudinal length during expansion of a stent-graft from a compressed state to an expanded state. For example, the stent-graft is placed over a cover that provides resistance to expansion of the balloon during inflation, which reduces longitudinal compressing forces exerted on the stent-graft.
