Abstract

A tubular synthetic endoluminal graft having at least one radiopaque ink marker pattern to radiographically delineate the surface of the graft cloth. The radiopaque ink marker includes a matrix of ink dots defining an annular band about a circumference of the graft. The endoluminal graft including at least one stent attached to the graft. The at least one stent may overlap or be positioned adjacent the radiopaque ink marker. The radiopaque ink marker may be utilized to facilitate creation of a fenestration in the side wall of the graft in situ to perfuse a side branch vessel.

Claims

1. A graft for implantation within a body lumen, the graft comprising:

a tubular body of a graft material;

a radiopaque ink marker pattern imprinted on the graft material of the tubular body, wherein the radiopaque ink marker includes a matrix of ink dots having a space between adjacent ink dots and the ink dots define an annular band around a circumference of the tubular body.

2. The graft of claim 1, wherein the annular band has a width of between 1-1.5 centimeters.

3. The graft of claim 1, wherein the space between adjacent ink dots is between 1-3 millimeters.

4. The graft of claim 1, further comprising:

at least one stent sutured to the tubular body.

5. The graft of claim 4, wherein the radiopaque ink marker is adjacent to the support member on the tubular body.

6. The graft of claim 4, wherein at least a portion of the support member overlaps with the matrix of ink dots of the radiopaque ink marker.

7. The graft of claim 1, wherein the radiopaque ink marker is partially opaque.

8. A graft for implantation within a body lumen, the graft comprising:

a graft material formed into a tubular body;

a first stent attached to the tubular body and a second stent attached to the tubular body, wherein an unsupported body portion of graft material extends between the first support member and the second support member; and

a radiopaque ink marker pattern imprinted on the graft material of the unsupported body portion of the graft.

9. The graft of claim 8, wherein the radiopaque ink marker defines an annular band around a circumference of the tubular body.

10. The graft of claim 9, wherein the first and second annular supports member are sutured to the tubular body.

11. The graft of claim 9, wherein the annular band has a width that is between 1-1.5 centimeters.

12. The graft of claim 8, wherein the radiopaque ink marker includes a matrix of dots having a space between adjacent dots of between 1-3 millimeters.

13. The graft of claim 8, wherein the first stent is attached to a proximal end of the tubular body and the second stent is attached to a distal end of the tubular body.

14. The graft of claim 8, wherein the radiopaque ink marker is partially opaque.

15. A method of creating a fenestration in a tubular graft in situ, the method comprising the steps of:

tracking a tubular graft to a target location within a body lumen, wherein the graft includes a first stent attached to the graft, a second stent attached to the graft, an unsupported body portion extending between the first support member and the second support member, and at least one radiopaque ink marker pattern imprinted on the unsupported body portion of the graft;

positioning the graft within the body lumen such that the radiopaque ink marker is aligned with an ostium of a side branch vessel;

radially expanding the graft;

tracking a puncture device to the radially expanded graft until a distal end of the puncture device is adjacent to the radiopaque ink marker; and

creating a fenestration in the unsupported body portion of the graft to perfuse the side branch vessel.

16. The method of claim 15, further comprising:

indenting the graft with the distal end of the puncture device prior to creating a fenestration in the unsupported body portion of the graft.

17. The method of claim 15, wherein the radiopaque ink marker defines an annular band around a circumference of the tubular body.

18. The method of claim 17, wherein the annular band has a width of between 1-1.5 centimeters.

19. The method of claim 15, wherein the radiopaque ink marker includes a matrix of dots having a space between adjacent dots of between 1-3 millimeters.

20. The method of claim 15, wherein the radiopaque ink marker is partially opaque.
