Abstract
Abstract An endovascular support assembly, or stent assembly, and a covered endovascular support assembly, or stent-graft assembly, with caps on either or both ends for improved and uniform deployment of the assembly. Additionally, the caps serve to capture the graft material between the caps and the endovascular support device or stent.
