1. A stent delivery device comprising:

  • a segmented sheath capable of overlying a radially expandable endoprosthesis stent with said stent being in a compressed condition;

    said segmented sheath capable of restraining said stent from radial expansion; and

    said segmented sheath comprising a plurality of adjacent flaps that in combination are capable of completely encircling said compressed stent, each of said flaps being axially slidable with respect to all other said flapswherein a first of said flaps has a projection running along at least part of its length, and said projection is adapted to engage a corresponding structure on an adjacent second one of said flaps to form a slidable coupling configured to permit said first and second flaps to slide axially with respect to one another while restraining at least a portion of the stent from expanding radially; and

    wherein each of said first and second flaps has a longitudinal edge adjacent to the longitudinal edge of the other of said first and second flaps, and wherein said adjacent longitudinal edges are connected by said slidable coupling.
