Abstract:
1. 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 one or more links that connect a proximal bend of the first branch support structure to a distal bend of the first or main branch structure, wherein the one or more links comprise at least one metal loop or ring configured to permit pivotable movement of the first branch support with respect to the first or main branch structures.
