<p>In accordance with the present invention there is provided a precursor stent for implantation within the body of a patient, particularly for treating abdominal aortic aneurysms. The stent is designed to receive a pair of grafts placed side by side within the interior of the stent. The stent includes a substantially cylindrical and expandable member having a proximal end, a distal end, a longitudinal axis extending therebetween and an interior. The stent further includes an occlusive member attached to the expandable member. The occlusive member at least partially occludes a passageway or stent lumen which extends through the interior of the expandable member extending between its distal end and proximal end. The occlusive member has an opening extending therethrough designed to receive a guidewire for one of the grafts. Therefore, when the guidewire for the other graft is introduced, after deployment of the stent within a body, it will go through the portion of the interior not covered by the occlusive member. This helps to ensure proper side by side placement of the two grafts. <IMAGE></p> |
