Abstract

Claims (23)

1. A vascular prosthesis, comprising:

a) a luminal graft component having a proximal open end, a distal open end, and defining a main lumen extending from the proximal open end to the distal open end, the luminal graft component defining at least one fenestration; and

b) a crimped adapter at the at least one fenestration, the crimped adapter including a perimeter section that is fixed to the luminal graft component and seals the fenestration, the crimped adapter also defining an opening with a diameter smaller than the fenestration and including a crimped portion of generally concentric folds arranged concentrically within the perimeter section and about the opening,

wherein the concentric folds are coplanar, and

whereby the crimped adapter can adapt to positioning of a branch prosthesis extending through the opening by flexation of the folds to thereby move the opening relative to the perimeter section, and

wherein the concentric folds of the crimped adapter have a periodicity of about 1 mm to about 5 mm.

2. The vascular prosthesis of claim 1 , wherein the concentric folds of the crimped adapter have an amplitude in a range of between about 1 mm and about 10 mm.

3. The vascular prosthesis of claim 1 , wherein the perimeter section of the crimped adapter includes first surface, with a crimped portion raised from the first surface.

4. The vascular prosthesis of claim 3 , wherein the first surface faces an outside surface of the luminal graft component.

5. The vascular prosthesis of claim 3 , wherein the folds of the crimped adapter have a period in a range of between about 2 mm to about 4 mm.

6. The vascular prosthesis of claim 1 , wherein the crimped adapter includes between about 3 folds to about 10 folds.

7. The vascular prosthesis of claim 1 , wherein the crimped portion is circular.

8. The vascular prosthesis of claim 1 , wherein the crimped portion is round.

9. The vascular prosthesis of claim 1 , wherein the crimped portion is oval.

10. The vascular prosthesis of claim 1 , wherein the crimped portion is elliptical.

11. The vascular prosthesis of claim 1 , wherein the crimped portion is rectangular.

12. The vascular prosthesis of claim 1 , wherein the crimped portion is rectilinear.

13. The vascular prosthesis of claim 1 , wherein the crimped adapter includes a ring affixed to a circumference thereof.

14. The vascular prosthesis of claim 1 , further including a plurality of radial stents distributed longitudinally along the luminal graft component, the radial stents including struts that define proximal apices and distal apices.

15. The vascular prosthesis of claim 1 , wherein the crimped adapter includes at least one member selected from the group consisting of polytetrafluoroethylene, polyethylene terephthalate, polymer and silicon.

16. The vascular prosthesis of claim 1 , wherein the vascular prosthesis includes one fenestration and one crimped adapter.

17. The vascular prosthesis of claim 1 , wherein the vascular prosthesis includes two fenestrations and two or more crimped adapters.

18. The vascular prosthesis of claim 1 , further including at least one branch prosthesis, each branch prosthesis having a proximal end and a distal end, and extendable through the opening of the crimped adapter and the fenestration of the luminal graft component.
