1. A expandable bifurcation graft, comprising:
- a first tubular body, having a superior end and an inferior end;
a second tubular body, having a superior end and an inferior end; and
a magnetic connection between the superior end of the first tubular body and the superior end of the second tubular body;
wherein the superior ends of the first and second tubular bodies are configured such that when the tubular bodies are connected by the magnetic connection about into a side by side relationship, each of the superior ends defines a semi circular opening.

Abstract
Disclosed is a method and apparatus for treating bifurcations of the vascular system, such as abdominal aneurysms at the bifurcation of the aorta and iliac arteries. A tubular implant having a first section, a second section and a magnetic connection therebetween is positioned across the bifurcation such that the proximal ends of the first and second sections extends into a first iliac and a second iliac respectively. Deployment catheters are also disclosed.
