1. An endoluminal graft comprising:
- a tube of graft material having a first end, a second end, and a frangible section disposed between the first and second ends;
the tube including a first leg having a proximal end disposed adjacent one side of the frangible section and a distal end disposed at the first end of the tube, and a second leg integral with and adjacent to the first leg, the second leg having a proximal end disposed adjacent the other side of the frangible section and a distal end disposed at the second end of the tube;
where the frangible section comprises a series of perforations in the graft material perpendicular to a longitudinal axis of the tube and extending at least partially circumferentially about the tube;
where the frangible section connects the first leg and the second leg so that the first and second legs share a common lumen;
where each of the legs comprises at least one expandable stent secured to the graft material; and
where the frangible section is at least partially breakable upon the application of a bending force perpendicular to the longitudinal axis of the tube.

Abstract
An endoluminal graft includes a unitary tube of graft material forming two adjacent legs that are integral and monolithic to each other. The graft can be part of a prosthesis assembly for treatment of branched vascular systems and can function as an integral bifurcated leg extension prosthesis in combination with a main bifurcated prosthesis. In treating abdominal aortic aneurysms, the graft can be deployed within both iliac arteries.

12. An endoluminal prosthesis, comprising:
-
a main body having a proximal end and a distal end and comprising a bifurcation, a first limb, and a second limb; and a tube of graft material insertable into at least one of the proximal and distal ends, the tube of graft material comprising a frangible section, a first leg disposed adjacent one side of the frangible section, and a second leg, integral with and adjacent to the first leg, disposed adjacent the other side of the frangible section; where the frangible section comprises a series of perforations in the graft material perpendicular to a longitudinal axis of the tube, extends at least partially circumferentially about the tube, and connects the first leg and the second leg so that the first and second legs share a common lumen where the frangible section is at least partially breakable upon the application of a bending force perpendicular to the longitudinal axis of the tube. - View Dependent Claims (13, 14, 15)

16. An endoluminal graft comprising:
-
a tube of graft material having a first end, a second end, and a single, continuous lumen disposed between the first and second ends; a first expandable stent secured to the graft material and a second expandable stent secured to the graft material; and a means for at least partially tearing the tube upon the application of a bending force perpendicular to the longitudinal axis of the tube, whereby application of a bending force on the tube separates the tube into; a first leg portion comprising the first expandable stent and having a proximal end, a distal end disposed at the first end of the tube, and a first lumen disposed between the proximal and distal ends of the first leg portion; a second leg portion, integral and monolithic with the first leg portion, comprising the second expandable stent and having a proximal end, a distal end disposed at the second end of the tube, and a second lumen disposed between the proximal and distal ends of the second leg portion. - View Dependent Claims (17)
