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; 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.

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.

10. 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. - View Dependent Claims (11, 12, 13)
