Abstract
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. <IMAGE>

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
256 words
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mechanism for causing movement of the first part with respect to the second part to thereby permit the capsule to be withdrawn from over the graft and permitting the retention means to retain the graft in a position so that it is ejected from the capsule as the first part is moved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.
Claim 2
Dependent Claim
28 words
A device as claimed in Claim 1 wherein said graft has expandable anchor means capable of moving outwardly as soon as the expandable anchor means clears the capsule.
Claim 3
Independent Claim
27 words
A device as claimed in Claims 1 or 2 wherein said means for causing relative movement between the first and second parts includes a rack and pinion.
Claim 4
Independent Claim
38 words
A device as claimed in any one of Claims 1 through to 3 wherein said control mechanism includes means for preventing longitudinal movement of the flexible elongate tubular member of the balloon catheter relative to the control mechanism.
Claim 5
Dependent Claim
51 words
A device as claimed in Claim 4 wherein said control mechanism includes means for operating on said means for preventing longitudinal movement of the flexible elongate tubular member of the balloon catheter to permit longitudinal movement of the flexible elongate tubular member of the balloon catheter relative to the control mechanism.
Claim 6
Independent Claim
67 words
A device as claimed in any one of Claims 1 through to 5 wherein said graft is in the form of a main body and first and second legs adjoining the main body and extending away from the main body to provide a bifurcation, one of said legs being folded over and lying generally parallel to the main body when the graft is disposed within the capsule.
Claim 7
Dependent Claim
23 words
A device as claimed in Claim 6 together with a lead tube connected to the folded-over leg and extending out of said capsule.
Claim 8
Dependent Claim
65 words
A device as claimed in Claim 7 further including a single pull line secured to said leg and extending through said leg and having its free ends knotted together, said lead tube extending over the pull line into the vicinity of said capsule and means formed in the tube engaging the knot to prevent the lead tube from being pulled off of the pull line.
Claim 9
Dependent Claim
20 words
A device as claimed in Claim 8 wherein said lead tube is provided with a cutout proximal of the knot.
