  • a primary graft body, said primary graft body having a primary graft flow lumen therethrough, said primary graft body comprising a proximal end and a distal end; and

    a supplemental graft body, said supplemental graft body having a secondary graft flow lumen therethrough, said supplemental graft body comprising a first end and a second end, said first end of said supplemental graft body being dockable to said distal end of said primary graft body while inside of a vessel to define a single flow lumen which transfers substantially all flow between said primary graft flow lumen and said secondary graft flow lumen;

    wherein said primary graft body is carried by a plurality of separated wire hoops each having a sinuous configuration with a plurality of apices, said plurality of separated wire hoops each having a circumference that lies in a plane substantially perpendicular to a common axis and each being axially displaced in a tubular configuration along the common axis;

    wherein said plurality of separated wire hoops of said primary graft body includes hoops associated with said proximal end and said distal end that have a unit width between said apices and intermediate hoops between the loops associated with said proximal end and said distal end that have a width between said apices greater than the unit width; and

    wherein each of said plurality of separated wire hoops comprises two opposing ends, said ends on adjacent wire loops being joined together on the outside surface of said primary graft body at a number of juxtaposed apices.
