A device and method for controlling the positioning of one or more flexible stent graft fenestrations are disclosed. The stent graft may be for repair of an aneurysm proximate a branch vessel. The stent graft includes a primary graft having an anchoring device, a graft material forming a central lumen and at least one flexible fenestration in a side wall thereof. A fenestration positioning member extends within the stent graft central lumen and has a distal end removably attached to the stent graft proximate the at least one flexible fenestration. The fenestration positioning member may include a tubular member having a wire extending there through, wherein a sidewall of the tubular member includes an aperture through which a loop of the wire extends and removably attaches to the fenestration. Alternatively, the fenestration positioning member may include a tubular member having a suture extending there through, wherein a loop of the suture distally extends from a distal end of the tubular member and is removably attached to the fenestration. The stent graft may include one or more flexible fenestrations, each fenestration having a fenestration positioning member removably attached thereto. |
