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.

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.

[ We claim:] [1.] 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; anda 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.
