Method for deploying a stent device having a main body, a proximal coupling, and a distal coupling

Abstract

A method for deploying a stent device having a main body, a proximal coupling, and a distal coupling. The method includes extending a first guidewire in an aorta, extending a second guidewire in a brachiocephalic artery, and extending a third guidewire in an aortic branch vessel. The method further includes tracking the stent device along the first, second, and third guidewires. During the tracking step, the first guidewire extends through the main body, the second guidewire extends through the proximal coupling, and the third guidewire extends through the distal coupling. The method also includes deploying the main body within the aorta with the proximal coupling aligning with the brachiocephalic artery and the distal coupling aligning with the aortic branch vessel.
