2. A tubular wire support for combination with a sheath to produce a bifurcated endoluminal prosthesis, said tubular wire support comprising:
-
a main body support structure having a proximal end, a distal end and a central lumen extending therethrough, the support structure comprising at least a first and second axially adjacent tubular segments, each segment comprising a plurality of wall struts connected by proximal and distal bends;
a first branch support structure having a proximal end, a distal end and a central lumen therethrough connected to the main body support structure, the first branch structure comprising at least a first and second axially adjacent tubular segments, each segment comprising a plurality of wall struts connected by proximal and distal bends;
a second branch support structure having a proximal end, a distal end and a central lumen extending therethrough, connected to the main body support structure, the second branch structure comprising at least a first and second axially adjacent tubular segments, each segment comprising a plurality of wall struts connected by proximal and distal bends;
wherein the first and second branch support structures are pivotably attached to the main body support structure by a plurality links that connect a proximal bend of the first branch support structure to a distal bend of the first or second branch structure. - View Dependent Claims (3, 5, 6)
