Patent ID: 6921414

Claim:
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.
