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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
213 words
A device for deploying a graft having a bifurcation, the device comprising: a capsule catheter formed from a flexible elongate tubular member having proximal and distal extremities; a capsule mounted proximate the distal extremity of the tubular member of said capsule catheter, said capsule having an open end; a graft having a bifurcation disposed within said capsule; a balloon catheter formed from a flexible elongate tubular member having proximal and distal extremities and extending through said graft, through said capsule and through the tubular member of said capsule catheter; a balloon secured proximate the distal extremity of the tubular member of said balloon catheter; retention means carried by the tubular member of said balloon catheter for engaging said graft; and a control mechanism including a handle having first and second parts movable relative to each other, wherein the proximal extremity of the tubular member of said capsule catheter is secured to the first part, and wherein the tubular member of said balloon catheter extends through the first part, said control mechanism further including means for causing relative movement of the first part with respect to the second part so as to withdraw said capsule from said graft, wherein said retention means retains said graft in a fixed position relative to said balloon catheter.
Claim 2
Independent Claim
213 words
A device for deploying a graft having a bifurcation, the device comprising: a capsule catheter formed from a flexible elongate tubular member having proximal and distal extremities; a capsule mounted proximate the distal extremity of the tubular member of said capsule catheter, said capsule having an open end; a graft having a bifurcation disposed within said capsule; a balloon catheter formed from a flexible elongate tubular member having proximal and distal extremities and extending through said graft, through said capsule and through the tubular member of said capsule catheter; a balloon secured proximate the distal extremity of the tubular member of said balloon catheter; retention means carried by the tubular member of said balloon catheter for engaging said graft; and a control mechanism including a handle having first and second parts movable relative to each other, wherein the proximal extremity of the tubular member of said capsule catheter is secured to the first part, and wherein the tubular member of said balloon catheter extends through the first part, said control mechanism further including means for causing relative movement of the first part with respect to the second part so as to withdraw said capsule from said graft, wherein said retention means retains said graft in a fixed position relative to said balloon catheter.
Claim 3
Dependent Claim
27 words
A device as 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 4
Dependent Claim
24 words
A device as in claim 1 wherein said means for causing relative movement between the first and second parts includes a rack and pinion.
Claim 5
Dependent Claim
31 words
A device as in claim 1 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 6
Dependent Claim
50 words
A device as 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 7
Dependent Claim
60 words
A device as in claim 1 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 8
Dependent Claim
22 words
A device as in claim 6 together with a lead tube connected to the folded-over leg and extending out of said capsule.
Claim 9
Dependent Claim
64 words
A device as in claim 7 together with 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 10
Dependent Claim
19 words
A device as in claim 8 wherein said lead tube is provided with a cutout proximal of the knot.
Claim 11
Independent Claim
212 words
A device for deploying a graft, the device comprising: a capsule catheter formed from a flexible elongate tubular member having proximal and distal ends; a capsule mounted proximate the distal end of said capsule catheter, said capsule having a closed proximal end and an open distal end; a bifurcated graft disposed within said capsule, said bifurcated graft configured with a main tubular body, a first leg and a second leg, said bifurcated graft including a first attachment system secured to the main tubular body; a balloon catheter formed from a flexible elongate tubular member having proximal and distal ends, said balloon catheter extending through said capsule catheter and through said capsule; a balloon formed on the tubular member of said balloon catheter; and a control mechanism including a handle and an assembly disposed within the handle, wherein the proximal extremity of said capsule catheter is secured to the assembly such that the tubular member of said balloon catheter extends through the assembly and through the handle, said control mechanism further including means for retaining said balloon catheter stationary relative to the handle, and wherein the assembly is configured to cause relative movement of the capsule catheter with respect to the handle so as to move said capsule relative to said balloon catheter.
Claim 12
Independent Claim
212 words
A device for deploying a graft, the device comprising: a capsule catheter formed from a flexible elongate tubular member having proximal and distal ends; a capsule mounted proximate the distal end of said capsule catheter, said capsule having a closed proximal end and an open distal end; a bifurcated graft disposed within said capsule, said bifurcated graft configured with a main tubular body, a first leg and a second leg, said bifurcated graft including a first attachment system secured to the main tubular body; a balloon catheter formed from a flexible elongate tubular member having proximal and distal ends, said balloon catheter extending through said capsule catheter and through said capsule; a balloon formed on the tubular member of said balloon catheter; and a control mechanism including a handle and an assembly disposed within the handle, wherein the proximal extremity of said capsule catheter is secured to the assembly such that the tubular member of said balloon catheter extends through the assembly and through the handle, said control mechanism further including means for retaining said balloon catheter stationary relative to the handle, and wherein the assembly is configured to cause relative movement of the capsule catheter with respect to the handle so as to move said capsule relative to said balloon catheter.
Claim 13
Dependent Claim
36 words
The device of claim 10, wherein said bifurcated graft further includes a second attachment system secured to the first leg proximate the opening of the first leg, wherein said attachment system is disposed within said capsule.
Claim 14
Dependent Claim
32 words
The device of claim 11, further including a pull line secured to the second leg of said bifurcated graft proximate the opening of the second leg and partially disposed within said capsule.
Claim 15
Dependent Claim
17 words
The device of claim 10, wherein the assembly of said control mechanism includes a rack and pinion.
