Endovascular graft having bifurcation and apparatus and method for deploying the same
First Claim
1. A graft having a bifurcation for repairing an aortic aneurysm close to or involving the aortic bifurcation in a patient comprising a main tubular body and first and second tubular legs joined to said main body in a bifurcation, said main body and said legs being formed of a flexible surgically implantable material, said main body and said first and second legs each having an opening therein in communication with the other openings, expandable anchor means secured to the main body adjacent the opening in the main body and additional expandable anchor means secured to one of said legs adjacent the opening in said one leg.

Abstract
Graft having a bifurcation for repairing an aneurysm in the vicinity of an aortic bifurcation in a patient comprising a main tubular body and first and second tubular legs joined to said main body in a bifurcation. The main body and the legs are formed of a flexible surgically implantable material. The main body and each of the first and second legs having an opening therein in communication with the other openings. Expandable spring attachments are secured to the main body adjacent the opening in the main body. An additional expandable spring attachment is secured to one of said legs adjacent the opening in said one leg.

- 1. A graft having a bifurcation for repairing an aortic aneurysm close to or involving the aortic bifurcation in a patient comprising a main tubular body and first and second tubular legs joined to said main body in a bifurcation, said main body and said legs being formed of a flexible surgically implantable material, said main body and said first and second legs each having an opening therein in communication with the other openings, expandable anchor means secured to the main body adjacent the opening in the main body and additional expandable anchor means secured to one of said legs adjacent the opening in said one leg.
- 6. In a major deployment device, a capsule catheter and a balloon catheter, said capsule catheter comprising a flexible elongate tubular member having proximal and distal extremities, a flexible capsule mounted on the distal extremity of the flexible elongate tubular member, said capsule having an open end, a graft disposed within the capsule, said balloon catheter comprising a flexible elongate tubular member having proximal and distal extremities, balloon secured to the distal extremity of the flexible elongated tubular member of the balloon catheter, said flexible elongated tubular member of the balloon catheter extending through the graft and through the capsule in which the graft is disposed and through the flexible elongated tubular member secured to the capsule, retention means carried by the flexible elongated tubular member of the balloon catheter and engaging the graft, a control mechanism having a handle adapted to be grasped by a human hand and having first and second parts movable relative to each other, means for securing the flexible elongate tubular member of the capsule catheter to the first part, said flexible elongate tubular member of the balloon catheter extending through said first part and through said control mechanism and means carried by the control mechanism for causing movement of the first part with respect to the second part to thereby permit the capsule to be withdrawn from over the graft and permitting the retention means to retain the graft in a position so that it is ejected from the capsule as the first part is moved relative to the second part.
- 15. In a minor deployment device, a capsule catheter and a balloon catheter, said capsule catheter comprising a flexible elongated tubular element having proximal and distal extremities, a capsule secured to the distal extremity, a fitting provided on the proximal extremity, the balloon catheter comprising a flexible elongate tubular element having proximal and distal extremities, a balloon carried by the distal extremity, the balloon being disposed distally of the capsule and having the flexible elongate tubular member of the balloon catheter extending through the capsule and through the flexible elongate tubular member of the capsule catheter and a fitting mounted on the proximal extremity of the flexible elongate tubular member of the balloon catheter for inflating and deflating the balloon, said flexible elongate tubular member of the catheter having retention means provided thereon and disposed within the capsule, and an expandable spring attachment means disposed within the capsule and being in engagement with the retention means.
- 17. In a method for deploying a graft having bifurcation with a main body and first and second legs for deployment across an aortic bifurcation of a patient to repair an aneurysm close to or involving the aortic bifurcation and the associated first and second iliac arteries, folding the second leg of the graft so it lies substantially parallel to the main body of the graft to provide a folded-over second leg, introducing the graft with the folded-over second leg through the first iliac artery until the graft is disposed proximal of the bifurcation, securing the proximal extremity of the graft with the first leg of the graft being disposed in the first iliac artery, pulling down the folded-over second leg into the second iliac artery, securing the distal extremity of the first leg in the first iliac artery and thereafter securing the second leg of the graft in the second iliac artery.
