1. A vascular dissection-treating endoluminal prosthesis comprising:

  • a coiled, generally helically extending body;

    a graft material covering the entire coiled body to create a coiled stent graft movable between radially expanded and radially contracted conditions;

    the coiled body comprising laterally spaced-apart, longitudinally extending rail elements and transversely extending connector elements connecting the rail elements;

    said coiled stent graft having generally helically extending turns with first and second generally helically extending edges and a width measured perpendicular to said edges, said stent graft placeable in the radially contracted condition for placement and in the radially expanded condition for use; and

    said stent graft, when in the radially expanded condition, constructed to have at most 2 turns and to press outwardly against a wall within an aortic arch of a patient so to force any separated intimal lining back against a remainder of the wall.
