Abstract:
A method for treating a tissue separation condition within a tubular body structure, the tissue separation condition comprising separated tissue defining a gap between the separated tissue and the remainder of the tubular body structure, comprising;placing an endoluminal prosthesis in a radially contracted condition at a tissue separation condition target site, the target site being an entry opening into a false lumen defined between the separated tissue of a dissection and the remainder of the tubular body structure, the endoluminal prosthesis comprising: a coiled body; a graft material covering at least a part of the coiled body to create a coiled stent graft movable between radially expanded and radially contracted conditions, said coiled stent graft comprising turns, said turns having edges and a width measured perpendicular to said edges, said stent comprising turns, said turns having 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 having in an average turns-width to stent graft length ratio from about 1 to 1 to about 1 to 4 when in the radially expanded condition; and expanding the stent graft towards the radially expanded condition thereby pressing against the separated tissue to help press the separated tissue against the remainder of the tubular body structure.
