Intraluminal vessel prosthesis system

A method for implantation of an intraluminal vascular prosthesis system into an aortic arch of a patient the intraluminal vascular prosthesis system including a hollow-cylindrical main vessel prosthesis, which has a lumen routed through the main vessel prosthesis, a first lumen end, a second lumen end, a hollow-cylindrical stent frame, with a prosthesis material secured thereon, a length L1 and a diameter D1, wherein the hollow-cylindrical main vessel prosthesis is configured and dimensioned for implantation in the region of the aortic arch and a descending aorta of the patient, and wherein the main vessel prosthesis has at least one hollow-cylindrical anchoring vessel prosthesis, which has a lumen routed through the anchoring vessel prosthesis, a first lumen end, a second lumen end, a hollow-cylindrical stent frame, with a prosthesis material secured thereon, a length L2 and a diameter D2, wherein the anchoring vessel prosthesis is securely attached within the lumen of the main vessel prosthesis, at least over part of the length L2 of the anchoring vessel prosthesis, and wherein the diameter D2 of the anchoring vessel prosthesis is at least 45% smaller than the diameter D1 of the main vessel prosthesis, and wherein the length L2 of the anchoring vessel prosthesis is shorter than the length L1 of the main vessel prosthesis, wherein the first lumen end of the main vessel prosthesis and the first lumen end of the anchoring vessel prosthesis are flush with one another, wherein the method comprises:

• inserting and releasing the main vessel prosthesis in a region of the aortic arch and of a descending aorta,
• inserting and releasing a side vessel prosthesis with its first lumen end in a subclavian artery and/or in a carotid artery and with its second lumen end at least partially in the lumen of the anchoring vessel prosthesis via the first lumen end of the anchoring vessel prosthesis.

A method for treating a vascular disease in an aortic arch of a subject in need thereof, the method comprising:

• providing an intraluminal vascular prosthesis system including a hollow-cylindrical main vessel prosthesis, which has a lumen routed through the main vessel prosthesis, a first lumen end, a second lumen end, a hollow-cylindrical stent frame, with a prosthesis material secured thereon, a length L1 and a diameter D1, wherein the hollow-cylindrical main vessel prosthesis is configured and dimensioned for implantation in the region of the aortic arch and a descending aorta of the patient, and wherein the main vessel prosthesis has at least one hollow-cylindrical anchoring vessel prosthesis, which has a lumen routed through the anchoring vessel prosthesis, a first lumen end, a second lumen end, a hollow-cylindrical stent frame, with a prosthesis material secured thereon, a length L2 and a diameter D2, wherein the anchoring vessel prosthesis is securely attached within the lumen of the main vessel prosthesis, at least over part of the length L2 of the anchoring vessel prosthesis, and wherein the diameter D2 of the anchoring vessel prosthesis is at least 45% smaller than the diameter D1 of the main vessel prosthesis, and wherein the length L2 of the anchoring vessel prosthesis is shorter than the length L1 of the main vessel prosthesis, wherein the first lumen end of the main vessel prosthesis and the first lumen end of the anchoring vessel prosthesis are flush with one another,
• inserting and releasing the main vessel prosthesis of the intraluminal vascular prosthesis system in a region of the aortic arch and of the descending aorta, inserting and releasing a side vessel prosthesis with its first lumen end in a subclavian artery and/or in a carotid artery and with its second lumen end at least partially in the lumen of the anchoring vessel prosthesis via the first lumen end of the anchoring vessel prosthesis, thereby treating the vascular disease.
