Abstract

A method of providing support in an aortic region. The method includes wrapping a landing band around an outside of a portion of an aortic vessel in a vicinity of a sinotubular junction (STJ) to form a wrapped portion of the aortic vessel. The method further includes securing the landing band to form a secured landing band. The method also includes endovascularly delivering a stent graft in a radially constricted configuration into the aortic vessel. The method also includes deploying the stent graft to a radially expanded configuration such that the stent graft contacts the wrapped portion of the aortic vessel. The method also includes connecting the stent graft in the radially expanded configuration to the secured landing band.

First claim

What is claimed is:

1. An aortic vessel support system comprising:
a landing band configured to wrap around a portion of an aortic vessel and having proximal and distal portions spaced apart from the portion of the aortic vessel, the proximal and distal portions of the landing band secured with fasteners at a secured portion spaced apart from the portion of the aortic vessel and having a landing band conical profile; and
a valve configured to be delivered endovascularly to the portion of the aortic vessel.

2. The aortic vessel support system of claim 1 , wherein the valve has a cone shape.

3. The aortic vessel support system of claim 1 , further comprising:
a stent graft configured to be delivered endovascularly to the portion of the aortic vessel.

4. A method of providing support in an aortic region, the method comprising:
wrapping a landing band around an outside of a portion of an aortic vessel to form a wrapped portion, the landing band having proximal and distal portions spaced apart from the wrapped portion;
securing the proximal and distal portions of the landing band with fasteners at a secured portion spaced apart from the wrapped portion to form a secured landing band;
endovascularly delivering and deploying a valve such that the valve contacts the wrapped portion; and
connecting the valve to the secured landing band.

5. The method of claim 4 , wherein the landing band has a landing band conical profile.

6. The method of claim 5 , wherein the valve has a valve conical profile following a contour of the landing band conical profile.

7. The method of claim 4 , wherein the valve extends beyond the proximal and distal ends of the landing band.

8. The method of claim 4 , further comprising:
endovascularly delivering and deploying a stent graft such that the stent graft contacts the wrapped portion; and
connecting the stent graft to the secured landing band.

9. The method of claim 4 , wherein the proximal and distal portions extend away from the wrapped portion.

10. A method of providing support in an aortic region, the method comprising:
wrapping a landing band around an outside of a portion of an aortic vessel in a vicinity of a sinotubular junction (STJ) to form a wrapped portion, the landing band having proximal and distal portions spaced apart from the wrapped portion, the landing band having a landing band conical profile;
securing the proximal and distal portions of the landing band with fasteners at a secured portion spaced apart from the wrapped portion to form a secured landing band;
endovascularly delivering a stent graft in a radially constricted configuration into the aortic vessel;
deploying the stent graft to a radially expanded configuration such that the stent graft contacts the wrapped portion; and
connecting the stent graft in the radially expanded configuration to the secured landing band.

11. The method of claim 10 , wherein the connecting step includes endovascularly connecting the stent graft in the radially expanded configuration to the secured landing band.

12. The method of claim 11 , wherein the connecting step includes endovascularly connecting the stent graft in the radially expanded configuration to the secured landing band via anchors.

13. The method of claim 12 , wherein the anchors are endoanchors.

14. The method of claim 12 , wherein the anchors are sutures, staples, and/or fasteners.

15. The method of claim 12 , wherein the anchors are shape-memory anchors.

16. The method of claim 10 , wherein the connecting step includes surgically connecting the stent graft in the radially expanded configuration to the secured landing band.

17. The method of claim 16 , wherein the connecting step includes surgically connecting the stent graft in the radially expanded configuration to the secured landing band via needles.

18. The method of claim 17 , wherein the connecting step includes surgically connecting the stent graft in the radially expanded configuration to the secured landing band via needles using a needle driver.

19. The method of claim 10 , wherein the secured portion following a line along proximal and distal widths of the proximal and distal portions, respectively.

20. The method of claim 10 , wherein the proximal and distal portions of the landing band extend away from the wrapped portion.
