DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a method for positioning all intraluminal graft into a bifurcating vessel such as an artery.
BACKGROUND ART
It is well known that through disease, arteries of humans are susceptible to the development of distended sacs known as aneurysms which are susceptible to rupture. Traditionally, aneurysms are treated by radical surgical graft replacement. This approach is risky for the patient and is, in many cases, not feasible due to other pre-existing disease states in the patient. More recently there have been a number of proposals for the intraluminal placement of an intraluminal graft bridging the aneurysms and thereby isolating an active arterial duct from the aneurysmal sac. One such arrangement is described in Australian Patent Application No. 78035/94.
Difficulties arise in the placement of such intraluminal grafts when the aneurysm extends from a single artery into one or more divergent arteries. In this case a so called "trouser graft" must be used. In such a graft a single tubular body bifurcates in a downstream direction into two smaller tubular bodies. The intention being that the single tubular body is placed in the single artery and the two smaller tubular bodies are respectively placed in the two divergent arteries (see, for example, U.S. Pat. No. 5,360,443 to Barone). In practice it has proven very difficult to effectively place a trouser graft.
DISCLOSURE OF THE INVENTION
According to a first aspect, the present invention consists in a method for positioning an intraluminal graft in a branching vessel within a patient's body, the vessel comprising a single pre-branching vessel branching into a pair of post-branching vessels, the method comprising: vessel through one of the post-branching vessels, the first intraluminal graft having a body having, at a first end, a tubular portion that is expandable into contact with a circumferential wall of the pre-branching vessel, and at a second end a bifurcation into first and second tubular graft extensions; tubular body, having an upstream end and a downstream end, into one of the post-branching vessels, moving the second graft until its upstream end is within, or surrounds, one of the tubular graft extensions of the first intraluminal graft and its downstream end is within the one of the post-branching vessels and causing the tubular body of the second intraluminal graft to form fluid conveying engagement with that tubular graft extension and with that vessel; and body, having an upstream end and a downstream end, into the other of the post-branching vessels, moving the third graft until its upstream end is within, or surrounds, the other of the tubular graft extensions of the first intraluminal graft and its downstream end is within the other of the post-branching vessels and causing the tubular body of the third intraluminal graft to form fluid conveying engagement with that tubular graft extension and with that vessel.
In a preferred embodiment of this aspect of the invention the first intraluminal graft is introduced through a first one of the post-branching vessels and the second intraluminal graft is introduced through the other of the post-branching vessels. The third intraluminal graft is then introduced through the first one of the post-branching vessels.
Instead of placing the bifurcated graft first it is possible to place one of the "leg" grafts first and to then position the bifurcated graft. Thus, in a second aspect, the invention consists in a method for positioning an intraluminal graft in a branching vessel within a patient's body comprising a single pre-branch vessel branching into a pair of post-branching vessels, the method comprising: body, having an upstream end and a downstream end, into one of the post-branching vessels and expanding its downstream end into contact with that vessel; post-branching vessels until it is positioned wholly within the pre-branching vessel, the second intraluminal graft having a body, having at a first end, a tubular portion that is expandable
