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 there through 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

1-10. -10. (canceled)

11. A heart valve assembly comprising:

an outer frame, wherein the outer frame is formed from a metallic material and defines a gridded configuration;

an inner frame that houses a prosthetic heart valve, wherein the inner frame is a graft covering extending radially outwardly of the prosthetic heart valve for providing sealing to the heart valve,

wherein the outer frame is secured to the graft covering by a plurality of stitches,

a sealing material positioned externally to the outer frame for providing sealing between the outer frame and a patient'"'"'s anatomical wall to prevent paravalvular leaks, wherein the sealing material includes a plurality of radially extending fibers that form a circumferential surface that extends outwardly of the outer frame.

12. The valve assembly of claim 11, wherein the fibers cover at least two circumferentially extending rows of grids formed in the gridded configuration.

13. The valve assembly of claim 11, wherein the fibers are engaged with the outer frame.

14. The valve assembly of claim 11, wherein the outer frame extends distally further than the prosthetic heart valve.

15. The valve assembly of claim 11, wherein the outer frame is a singular, integral component.

16. The valve assembly of claim 11, wherein the outer frame and the graft covering are attached by stitches at a top and bottom portion of the graft covering.

17. The valve assembly of claim 11, wherein the graft covering and the fibers are distinct elements.

18. The valve assembly of claim 11, wherein the valve assembly is delivered endovascularly.

19. The valve assembly of claim 11, wherein a seal is created between the inner frame and the outer frame.

20. The valve assembly of claim 11, wherein the valve assembly is balloon expandable.

21. The valve assembly of claim 11, wherein expansion of the valve assembly presses the sealing material against the aortic annulus of the patient.
