Device for endovascular aortic repair and method of using the same

An endograft device for endovascular repair of aortic aneurysms, comprising:

• a first endovascular prosthetic component comprising:
• an expandable stent frame;
• and
• a sealing cuff protruding from a lumen of the first prosthetic component,
• wherein blood flowing through the first prosthetic component is allowed to flow through at least one of the brachiocephalic artery, the left common carotid artery, and left subclavian artery when the endograft device has been implanted,
• a second endovascular prosthetic component secured to the first prosthetic component and comprising an expandable stent frame,
• wherein the first prosthetic component is configured to be placed into engagement with an arch of the patient's aorta,
• wherein the second prosthetic component is configured to be placed within the ascending aorta of a patient,
• wherein a portion of the second prosthetic component is received within the sealing cuff by an interference fit between the portion of the second prosthetic component and the sealing cuff,
• wherein the sealing cuff is covered with a graft material and the portion of the second prosthetic component received within the sealing cuff is covered with a graft material to cooperatively seal the first prosthetic component and the second prosthetic component by overlapping engagement of the graft material of the sealing cuff and the graft material of the portion of the second component,
• wherein the sealing cuff is positioned proximal the brachiocephalic artery when the first prosthetic component has been implanted in the patient,
• wherein the second prosthetic component is secured to the first prosthetic component within the sealing cuff,
• wherein the first prosthetic component is configured to extend across each of the brachiocephalic artery, the left common carotid artery, and left subclavian artery when implanted,
• wherein the first prosthetic component is implanted within the patient before the second prosthetic component is implanted.

• a second endovascular prosthetic component secured to the first prosthetic component and comprising an expandable stent frame,
• wherein the first endovascular prosthetic component is configured to be placed into engagement with an arch of the patient's aorta,
• wherein the second endovascular prosthetic component is configured to be placed within the ascending aorta of a patient,
• wherein a portion of the second endovascular prosthetic component is received within the sealing cuff by an interference fit between the portion of the second endovascular prosthetic component and the sealing cuff,
• wherein the sealing cuff is covered with a graft material and the portion of the second endovascular prosthetic component received within the sealing cuff is covered with a graft material to cooperatively seal the first endovascular prosthetic component and the second endovascular prosthetic component by overlapping engagement of the graft material of the sealing cuff and the graft material of the portion of the second prosthetic component,
• wherein the sealing cuff is configured to be positioned within the aorta when the first endovascular prosthetic component has been implanted in the patient,
• wherein the first endovascular prosthetic component extends across each of the brachiocephalic artery, the left common carotid artery, and left subclavian artery,
• wherein the first endovascular prosthetic component is configured to be implanted within the patient before the second prosthetic component is implanted,
• wherein the sealing cuff extends around a circumference of the portion of the second endovascular prosthetic component.

A method of repairing an aortic aneurysm, comprising:

• positioning an endograft device for endovascular repair of aortic aneurysms into the aortic arch of a patient, wherein the endograft device comprises:
• a first endovascular prosthetic component comprising:
• an expandable stent frame;
• and
• a sealing cuff protruding from a lumen of the first prosthetic component,
• wherein blood flowing through the first prosthetic component is allowed to flow through at least one of the brachiocephalic artery, the left common carotid artery, and left subclavian artery when the endograft device has been implanted,
• positioning a second endovascular prosthetic component into the ascending aorta, wherein the second endovascular prosthetic component comprises an expandable stent frame,
• wherein a portion of the second prosthetic component is received within the sealing cuff by an interference fit between the portion of the second prosthetic component and the sealing cuff,
• wherein the sealing cuff is covered with a graft material and the portion of the second prosthetic component received within the sealing cuff is covered with a graft material to cooperatively seal the first prosthetic component and the second prosthetic component by overlapping engagement of the graft material of the sealing cuff and the graft material of the portion of the second prosthetic component,
• wherein the sealing cuff is configured for being placed proximal of the brachiocephalic artery.
