Claims
- 1. A prosthesis comprising a stent graft having a proximal end, a distal end, a tubular wall defining a main lumen therethrough, at least one fenestration in the wall and at least one tube extending from the fenestration into the main lumen and in fluid communication with the main lumen, whereby an extension leg stent graft can be deployed from a branch vessel into the fenestration or from the main lumen into the branch vessel and into the tube to seal into the tube.
- 2. A prosthesis as in claim 1 wherein there are multiple fenestrations in the wall and multiple tubes extending into the main lumen from the multiple fenestrations.
- 3. A prosthesis as in claim 1 wherein the tube extending from the fenestration into the main lumen is angled, curved or bent to extend toward the proximal end of the stent graft.
- 4. A prosthesis as in claim 3 wherein the tube extending toward the proximal end of the stent graft is directed slightly angled to a longitudinal direction of the main lumen.
- 5. A prosthesis as in claim 1 wherein the tube extending from the fenestration into the main lumen is angled, curved or bent to extend toward the distal end of the stent graft.
- 6. A prosthesis graft as in claim 1 wherein the fenestration has a radiographic marker around its periphery to enable correct placement of the stent graft with respect to branch vessel.
- 7. A prosthesis as in claim 1 wherein the tube includes a flared guide associate therewith.
- 8. A prosthesis as in claim 7 wherein the flared guide extends exteriorly of the fenestration.
- 9. A prosthesis as in claim 7 wherein the flared guide extends interiorly of the fenestration.
- 10. A prosthesis as in claim 1 wherein the tubular wall includes a main wall portion and a leg portion and the fenestration is adjacent a junction between the main wall portion and the leg portion.
- 11. A prosthesis as in claim 1 wherein the tube includes a self-expanding stent.
- 12. A prosthesis as in claim 11 wherein the Z stent is disposed on the outside of the tube to provide a smooth inner socket surface into which the extension leg stent graft can be placed to enable sealing therebetween to occur.
- 13. A prosthesis as in claim 1 wherein the tube is fastened to the interior of the wall at a position spaced apart from the fenestration.
- 14. A prosthesis comprising a stent graft including a substantially tubular body portion providing a body fluid flow path, a first tubular leg extending from the body portion providing a first leg fluid flow path in communication with the body fluid flow path, an aperture in the tubular body portion adjacent the first tubular leg and a second tubular leg extending from the aperture into the tubular body portion, thereby providing a joining socket for a second leg extension and a second leg fluid flow path in communication with the body fluid flow path.
- 15. A prosthesis as in claim 14 wherein the second tubular leg extending into the body includes self expanding Z stents.
- 16. A prosthesis as in claim 15 wherein the Z stents are on the outside of the second tubular leg to provide a smooth inner socket surface into which a leg extension can be placed to enable sealing therebetween to occur.
- 17. A prosthesis as in claim 14 wherein the tube portion extending from the aperture in the body portion is of sufficient length so that flexibility is provided to a surgeon installing the device and in use the extension leg does not pull out of the second tubular leg.
- 18. A prosthesis as in claim 14 further including a flared guide associated with the second tubular leg to provide assistance for access of a deployment device when inserting an extension leg into the prosthesis.
- 19. A prosthesis as in claim 18 wherein the flared guide extends exteriorly of the fenestration.
- 20. A prosthesis as in claim 18 wherein the flared guide extends interiorly of the fenestration.
