Abstract

A system and method for treating a vascular condition includes a conduit having an elongate tubular member with an outer surface and an inner surface, the inner surface defines a conduit lumen. The system further includes at least one symmetry indicator attached to the elongate tubular member and a replacement valve device. The replacement valve device includes a prosthetic valve connected to an expandable support structure. The replacement valve device is positioned within the conduit lumen adjacent the inner surface.

Claims

1. A vascular valve replacement system, the system comprising:

a conduit comprising an elongate tubular member having an outer surface and an inner surface, the inner surface defining a conduit lumen;

at least one symmetry indicator attached to the elongate tubular member; and

a replacement valve device, the replacement valve device including a prosthetic valve connected to an expandable support structure, the replacement valve device positioned within the conduit lumen adjacent the inner surface.

2. The system of claim 1 wherein the at least one symmetry indicator comprises a framework having a plurality of spaced apart rings and a plurality of spaced apart elongate members attached to the plurality of rings.

3. The system of claim 2 wherein the plurality of rings and the plurality of elongate members comprise radiopaque filaments.

4. The system of claim 3 wherein the conduit comprises a woven material and the radiopaque filaments are interwoven into the woven material of the conduit.

5. The system of claim 3 wherein the conduit comprises a bioprosthesis and the radiopaque filaments are threaded through a conduit wall.

6. The system of claim 1 wherein the at least one symmetry indicator comprises a T-shaped radiopaque member attached to or imbedded within a wall of the conduit.

7. The system of claim 6 wherein the T-shaped radiopaque member comprises a plurality of filaments in a T-shaped configuration attached to the outer surface of the conduit.

8. The system of claim 1 wherein the T-shaped radiopaque member comprises a plurality of filaments in a T-shaped configuration attached to the inner surface of the conduit.

9. The system of claim 1 wherein the at least one symmetry indicator comprises a plurality of elongate members spaced apart around the circumference of the conduit, the plurality of elongate members parallel to a central axis of the conduit lumen.

10. The system of claim 1 further comprising a corrective device positioned within the conduit lumen between the inner surface of the conduit and an outer surface of the replacement valve device.

11. A prosthetic conduit device for treating a vascular condition, comprising:

a conduit comprising an elongate tubular member having an outer surface and an inner surface, the inner surface defining a conduit lumen; and

at least one symmetry indicator attached to the elongate tubular member.

12. The device of claim 11 wherein the at least one symmetry indicator comprises a framework having a plurality of spaced apart rings and a plurality of spaced apart elongate members attached to the plurality of rings.

13. The device of claim 12 wherein the plurality of rings and the plurality of elongate members comprise radiopaque filaments.

14. The device of claim 13 wherein the conduit comprises a woven material and the radiopaque filaments are interwoven into the woven material of the conduit.

15. The device of claim 13 wherein the conduit comprises a bioprosthesis and the radiopaque filaments are threaded through a conduit wall.

16. The device of claim 11 wherein the at least one symmetry indicator comprises a T-shaped radiopaque member attached to or imbedded within a wall of the conduit.

17. The device of claim 16 wherein the T-shaped radiopaque member comprises a plurality of filaments in a T-shaped configuration attached to the outer surface of the conduit.

18. The device of claim 11 wherein the at least one symmetry indicator comprises a plurality of elongate members spaced apart around the circumference of the conduit, the plurality of elongate members parallel to a central axis of the conduit lumen.

19. A method for treating a vascular condition, the method comprising:

inserting a conduit having a radiopaque conduit symmetry device into a target region of a vascular system, the conduit having an inner wall defining a conduit lumen;

visualizing the radiopaque conduit symmetry device;

determining conduit symmetry based on the visualization of the radiopaque conduit symmetry device;

delivering a stented valve into the conduit lumen, the stented valve including a prosthetic valve connected to an expandable support structure; and

expanding the stented valve into contact with the inner wall of the conduit.
