Abstract

An intraluminal vascular prosthesis assembly, having a hollow cylindrical body with a first end and a second end is provided. The assembly includes, at its first end, a first vascular prosthesis portion, and at its second end, a second vascular prosthesis portion which has only a prosthesis material. The vascular prosthesis assembly has a stent portion which is provided between the first vascular prosthesis portion and the second vascular prosthesis portion, the stent portion being free of prosthesis material to allow fluid flow therethrough and received within the aortic arch and spanning the brachiocephalic artery, left common carotid artery, and left subclavian artery when placed within the aortic arch of a patient.

Claims

1. An intraluminal vascular prosthesis assembly, having a hollow cylindrical body with a first end and a second end, comprising:

at its first end, a first vascular prosthesis portion; and

at its second end, a second vascular prosthesis portion;

wherein the vascular prosthesis assembly has a stent portion provided between the first vascular prosthesis portion and the second vascular prosthesis portion;

wherein the stent portion is received within the aortic arch;

wherein the stent portion defines a top portion that spans, but does not extend into, the brachiocephalic artery, left common carotid artery, and left subclavian artery when placed within the aortic arch of a patient; and

wherein a surface of the stent portion facing the brachiocephalic artery, left common carotid artery, and left subclavian artery is free of graft material to allow fluid flow therethrough.

2. The intraluminal vascular prosthesis assembly of claim 1, wherein the vascular prosthesis assembly is configured for implantation in the aortic arch, wherein the vascular prosthesis assembly can be transferred from a compressed state to an expanded state, and wherein the first vascular prosthesis portion and the second vascular prosthesis portion are designed for anchoring the vascular prosthesis assembly in the aorta.

3. The intraluminal vascular prosthesis assembly of claim 1, wherein the first vascular prosthesis portion and the stent portion are made from a self-expanding material.

4. The intraluminal vascular prosthesis assembly of claim 1, wherein the stent portion can be released in an expanded state in the area of the aortic arch.

5. The intraluminal vascular prosthesis assembly of claim 1, wherein the stent portion is a braided wire frame.

6. The intraluminal vascular prosthesis assembly of claim 1, wherein the stent portion defines a gridded pattern formed from a metal frame.

7. The intraluminal vascular prosthesis assembly of claim 1, wherein the second vascular prosthesis portion comprises wire frame material for supporting the vascular prosthesis portion.

8. The intraluminal vascular prosthesis assembly of claim 1, wherein the second vascular prosthesis portion defines a tapered portion for adjusting a diameter of the first vascular prosthesis.

9. The intraluminal vascular prosthesis assembly of claim 1, wherein the first vascular prosthesis portion is configured for engaging with a stent member placed in the aorta.

10. The intraluminal vascular prosthesis assembly of claim 1, wherein the second vascular prosthesis portion is configured for engaging with a stent member placed in the aorta.

11. The intraluminal vascular prosthesis assembly of claim 1, wherein the second vascular prosthesis portion is configured for engaging the ascending aorta when placed within the aortic arch of a patient.

12. The intraluminal vascular prosthesis according to claim 1, wherein a second prosthetic component is secured to a proximal end of the second vascular prosthesis in the patient'"'"'s aorta, and a proximal section of the second prosthetic component is expanded into engagement with the aortic annulus of the patient'"'"'s aorta such that a valve element secured to the proximal section is positioned in the aortic annulus proximal to the coronary arteries.

13. A method comprising:

providing an intraluminal vascular prosthesis assembly having a first vascular prosthesis portion at a first end and a second vascular prosthesis portion at a second end with a stent portion spanning between the first vascular prosthesis portion and the second vascular prosthesis portion;

positioning the first portion proximal to or within the descending aorta and the second portion within the ascending aorta such that the stent portion spans the brachiocephalic artery, left common carotid artery, and left subclavian artery of a patient;

wherein the stent portion defines a top portion that spans, but does not extend into, the brachiocephalic artery, left common carotid artery, and left subclavian artery when placed within the aortic arch of a patient; and

wherein a surface of the stent portion facing the brachiocephalic artery, left common carotid artery, and left subclavian artery is free of graft material to allow fluid flow therethrough.

14. The method of claim 13, comprising inflating the prosthesis assembly from a compressed state to an expanded state.

15. The method of claim 13, wherein the stent portion is a braided wire frame.

16. The method of claim 13, wherein the stent portion defines a gridded pattern formed from a metal frame.

17. The method of claim 13, comprising engaging the first vascular prosthesis portion to a stent member placed in the aorta, engaging the second vascular prosthesis portion with a stent member placed in the aorta, or both.

18. The method of claim 13, wherein the second vascular prosthesis portion is configured for engaging the ascending aorta.

19. The method of claim 13, including securing a second prosthetic component to a proximal end of the second vascular prosthesis in the patient'"'"'s aorta, and expanding a proximal section of the second prosthetic component into engagement with the aortic annulus of the patient'"'"'s aorta such that a valve element secured to the proximal section is positioned in the aortic annulus proximal to the coronary arteries.

20. An intraluminal vascular prosthesis assembly, having a hollow cylindrical body with a first end and a second end, comprising:

at its first end, a first vascular prosthesis portion; and

at its second end, a second vascular prosthesis portion comprising a valve element secured thereto;

wherein the vascular prosthesis assembly has a stent portion provided between the first vascular prosthesis portion and the second vascular prosthesis portion;

wherein the stent portion is received within the aortic arch;

wherein the stent portion defines a top portion that spans, but does not extend into, the brachiocephalic artery, left common carotid artery, and left subclavian artery when placed within the aortic arch of a patient;

wherein a surface of the stent portion facing the brachiocephalic artery, left common carotid artery, and left subclavian artery is free of graft material to allow fluid flow therethrough; and

wherein the stent portion is configured as a single continuous unit that engages the aortic arch across the entire length of the top portion and an entire length of an opposed bottom portion.
