1. A method of deploying a prosthetic assembly within an aortic arch, the method comprising the steps of:
advancing a first delivery system over a first guidewire and a second guidewire, the first guidewire pre-disposed within the aortic arch and the second guidewire pre-disposed within the brachiocephalic artery, wherein the first delivery system includes a proximal aortic stent-graft prosthesis disposed on a distal portion thereof and the proximal aortic stent-graft prosthesis is in a compressed configuration for delivery;
deploying the proximal aortic stent-graft prosthesis into an expanded configuration within a proximal portion of the aortic arch, wherein a coupling of the proximal aortic stent-graft prosthesis is disposed proximal to the ostium of the brachiocephalic artery, the coupling being frustoconically shaped and including an annular support wireform attached to and extending around an unattached end of the coupling,
advancing a second delivery system over the second guidewire, wherein second delivery system includes a first branch stent-graft prosthesis disposed on a distal portion thereof and the first branch stent-graft prosthesis is in a compressed configuration for delivery;
deploying the first branch stent-graft prosthesis into an expanded configuration within the brachiocephalic artery and through the coupling of the proximal aortic stent-graft prosthesis;
advancing a third delivery system over at least the first guidewire, wherein the third delivery system includes a distal aortic stent-graft prosthesis disposed on a distal portion thereof and the distal aortic stent-graft prosthesis is in a compressed configuration for delivery;
deploying the distal aortic stent-graft prosthesis into an expanded configuration within a distal portion of the aortic arch, wherein a proximal end of the distal aortic stent-graft prosthesis is disposed within the distal end of the proximal aortic stent-graft prosthesis to form an overlap between the proximal and distal aortic stent-graft prostheses.
