1. An intraluminal vascular graft structure for maintaining and repairing diseased or damaged vessels in animals comprising:

  • a flexible tubular body formed from a biocompatible material, said tubular body having an open proximal end for orientation upstream in a vessel, an open distal end for orientation downstream in said vessel and a longitudinal axis oriented between said open ends, said tubular body being inwardly compressible along the entirety of its length in a direction transverse said longitudinal axis and in a longitudinally non-lengthening manner to provide compression of said tubular body to a first reduced cross section and subsequent radially-outward expansion of said tubular body to a second expanded cross section;

    frame structure positioned to contact said tubular body with a portion of said frame structure oriented substantially in alignment with said longitudinal axis and with a portion positioned to extend around the circumferential dimension of said tubular body, said frame structure being formed and shaped to support said flexible tubular body circumferentially at said distal end and to rigidly support said flexible tubular body longitudinally from said distal end to said proximal end.
