An assembly comprising: a deployment device having: a rod translatable within an aorta of a patient and having an operator end and a distal end; a first release wire configured for releasing one or more radially constraining members (24; 52), and an uncovered stent device engaged with the deployment device in an initial configuration, the stent device comprising: a distal portion for being engageably received in the aortic arch of the patient and extending beyond the left subclavian artery when implanted; a stent portion fluidly engaged with the distal portion, wherein the stent portion is a braided stent member, wherein the stent portion is at least partially permeable and is configured to span a portion of the aortic arch to which the brachiocephalic trunk, left common carotid artery, and left subclavian artery attach when implanted in the aortic arch, such, that blood flows through the stent portion to each of the brachiocephalic trunk, left common carotid artery, and left subclavian artery; a proximal portion fluidly engaged with the stent portion; wherein the stent device includes a collar engaged with the proximal portion, the collar configured for being selectively engaged with the aorta and formed of a graft material; wherein the radially constraining members (24; 52) are configured to constrain a diameter of the stent device, wherein a diameter and a length of the stent device in a deployed configuration can be altered by axial translation of the rod and releasing one or more of the radially constraining members (24; 52) by translation of the first release wire. a deployment device having: a rod translatable within an aorta of a patient and having an operator end and a distal end; a first release wire configured for releasing one or more radially constraining members (24; 52), and a rod translatable within an aorta of a patient and having an operator end and a distal end; a first release wire configured for releasing one or more radially constraining members (24; 52), and an uncovered stent device engaged with the deployment device in an initial configuration, the stent device comprising: a distal portion for being engageably received in the aortic arch of the patient and extending beyond the left subclavian artery when implanted; a stent portion fluidly engaged with the distal portion, wherein the stent portion is a braided stent member, wherein the stent portion is at least partially permeable and is configured to span a portion of the aortic arch to which the brachiocephalic trunk, left common carotid artery, and left subclavian artery attach when implanted in the aortic arch, such, that blood flows through the stent portion to each of the brachiocephalic trunk, left common carotid artery, and left subclavian artery; a proximal portion fluidly engaged with the stent portion; wherein the stent device includes a collar engaged with the proximal portion, the collar configured for being selectively engaged with the aorta and formed of a graft material; a distal portion for being engageably received in the aortic arch of the patient and extending beyond the left subclavian artery when implanted; a stent portion fluidly engaged with the distal portion, wherein the stent portion is a braided stent member, wherein the stent portion is at least partially permeable and is configured to span a portion of the aortic arch to which the brachiocephalic trunk, left common carotid artery, and left subclavian artery attach when implanted in the aortic arch, such, that blood flows through the stent portion to each of the brachiocephalic trunk, left common carotid artery, and left subclavian artery; a proximal portion fluidly engaged with the stent portion; wherein the stent device includes a collar engaged with the proximal portion, the collar configured for being selectively engaged with the aorta and formed of a graft material; wherein the radially constraining members (24; 52) are configured to constrain a diameter of the stent device, wherein a diameter and a length of the stent device in a deployed configuration can be altered by axial translation of the rod and releasing one or more of the radially constraining members (24; 52) by translation of the first release wire.
