1. An axially telescoping prosthesis comprising:

  • a) a plurality of discrete radially expandable braided mesh bodies, each of said bodies being formed from a plurality of filaments that can slide across one another, each of the braided mesh bodies being configured to self-expand into at least one disc, each radially expandable braided mesh body defining a volume therein, the plurality of mesh bodies being axially displaceable with respect to one another; and

    b) a resilient member structurally distinct from the plurality of discrete mesh bodies, the resilient member being attached to and arranged to pass through a central region of the mesh bodies, the resilient member being configured and arranged to attach the plurality of discrete radially expandable braided mesh bodies to each other, wherein;

    (i) the radially expandable braided mesh bodies are selectively telescopically displaceable from one another along a central longitudinal axis of the prosthesis by stretching or relaxing the resilient member to accommodate differently sized anatomies, (ii) the resilient member is substantially co-axial with the central longitudinal axis of the prosthesis, and (iii) the resilient member is configured to cause the prosthesis to shorten along the axis and expand radially when the resilient member is relaxed.
