1. A system for delivering a vascular prosthesis, comprising:

  • an elongate body defining a longitudinal axis and comprising a proximal end, a distal end, and a plurality of delivery platforms disposed adjacent the distal end of the elongate body, each delivery platform of the plurality of delivery platforms comprising a recess extending distally of a radial protrusion;

    a balloon on an outer surface of the elongate body between a distal tip of the distal end of the elongate body and a distal-most delivery platform of the plurality of delivery platforms, the balloon being axially fixed in position on the elongate body with respect to the plurality of delivery platforms;

    a sheath having a proximal end, a distal end, and a sheath elongate body extending therebetween, the sheath being moveable relative to the elongate body from a first position in which the distal end of the sheath is disposed distally of the distal-most delivery platform of the plurality of delivery platforms to a second position in which the distal end of the sheath is disposed proximally of at least the distal-most delivery platform of the plurality of delivery platforms and the balloon;

    a plurality of self-expanding vascular prostheses, each vascular prosthesis of the plurality of self-expanding vascular prostheses comprising at least one radiopaque marker at a midline of the vascular prosthesis, and each vascular prosthesis of the plurality of self-expanding vascular prostheses being disposed about a corresponding delivery platform of the plurality of delivery platforms, and wherein each vascular prosthesis of the plurality of self-expanding vascular prostheses has a compression force curve being a measure of an amount of radial compression force required to compress the prosthesis along a range of outer diameters, and has an expansion force curve being a measure of an amount of radial expansion force exerted by the prosthesis when the prosthesis self-expands along the range of outer diameters, wherein the range of outer diameters is at least about 2 mm, and wherein a difference between the compression force curve and the expansion force curve at any given diameter along the range of outer diameters is no more than about 2 Newtons (N);

    wherein the system is configured to separately place at least two self-expanding vascular prostheses of the plurality of self-expanding vascular prostheses, one at a time, at a treatment zone at spaced apart locations along a vessel wall; and

    wherein the balloon is configured for post deployment dilation of the at least two placed self-expanding vascular prostheses of the plurality of self-expanding vascular prostheses, the balloon being configured to be positioned within one of the at least two placed self-expanding vascular prostheses of the plurality of self-expanding vascular prostheses and inflated to engage the one placed self-expanding vascular prosthesis of the at least two placed self-expanding vascular prostheses with outward pressure from an outer surface of the balloon and to enhance placement of the one placed self-expanding vascular prosthesis of the at least two placed self-expanding vascular prostheses against the vessel wall; and

    wherein the outer sheath is configured to cover the balloon when uninflated during advancement of the balloon within a vessel comprising the vessel wall.
