1. A method comprising:
identifying a dissection within an ascending aorta of a patient;
extending a stent device engaged with a deployment apparatus that includes a guide rod, wherein the deployment apparatus is configured for expanding and contracting the stent device,
wherein the stent device includes a first end that is covered by a non-porous graft material, wherein the first end includes a constraining member for constraining a diameter thereof,
wherein the stent device includes a medial, uncovered portion and an uncovered second end;
wherein the medial, uncovered portion and uncovered second end are free of a non-porous graft material along an entire circumference thereof;
expanding the first end of the stent device after translating the deployment apparatus until the first end is positioned about the identified dissection;
wherein the medial, uncovered portion of the stent device is positioned to span one or more branches fluidly coupled to the aortic arch, wherein the medial portion spans, but does not extend into the one or more branches fluidly coupled to the aorta,
expanding a remainder of the stent device by translating the deployment apparatus to expand or retract the stent device to adjust its length, diameter and wall apposition to engage the remainder with the patient's aorta,
wherein the stent device is a continuous, connected singular stent,
wherein the deployment apparatus comprises a sheath for housing the stent device and the guide rod passes through a center therethrough for deploying the stent device at an operational site,
wherein the sheath constrains the second end of the stent device in a compressed state,
wherein the constraining member constrains first end of the stent device in a compressed state after removal of the sheath until release of the constraining member, and
wherein the guide rod carries the stent device and is removable through a center of the stent device when the stent device is in an expanded state and positioned within the aortic arch of the patient upon removal of the sheath.
