WHAT IS CLAIMED IS:

1. An endoluminal prosthesis comprising:

a scaffold having a plurality of circumferential rings patterned from a non-degradable material, said scaffold being configured to expand from a crimped configuration to an expanded configuration, wherein attachment points on at least some adjacent circumferential rings are joined by circumferentially separable axial links;

wherein at least some of the axial links comprise a first segment and a second segment, wherein the first and second segments are divided by an axially extending dividing line, are circumferentially interlocked to inhibit circumferential separation thereof while the scaffold is in the crimped configuration, and are configured to deform to circumferentially unlock when the scaffold is in the expanded configuration; and

wherein the circumferential rings separate at the attachment points while each segment of the axial link remains attached to said attachment points after the segments have unlocked.

2. An endoluminal prosthesis as in claim 1, wherein the circumferentially separable axial links extend between crowns on adjacent circumferential rings.

3. An endoluminal prosthesis as in claim 1, wherein the circumferentially separable axial links extend between struts on adjacent circumferential rings.

4. An endoluminal prosthesis as in claim 1, wherein the circumferentially separable axial links extend between a crown on one circumferential rings and a struts on an adjacent circumferential rings.

5. An endoluminal prosthesis as in claim 1, wherein said at least some axial links are arranged in an axial line along the scaffold.

6. An endoluminal prosthesis as in claim 1, wherein said at least some axial links are arranged in a helical line along the scaffold.

7. An endoluminal prosthesis as in claim 1, wherein said at least some axial links are arranged in two lines along the scaffold.

8. An endoluminal prosthesis as in claim 1, wherein said at least some axial links are arranged in three lines along the scaffold.

9. An endoluminal prosthesis as in claim 1, wherein at least a portion of the axially extending dividing line is non-linear.

10. An endoluminal prosthesis as in claim 1, wherein the entire axially extending dividing line is non-linear

11. An endoluminal prosthesis as in claim 10, wherein the axially extending dividing line comprises includes one or morea curved sections and one or more linear section.

12. An endoluminal prosthesis as in claim 11, wherein the curved section includes regions of different curvature.

13. An endoluminal prosthesis as in claim 11, wherein the curved section includes regions of reversing curvature.

14. An endoluminal prosthesis as in claim 11, wherein the scaffold has first and second ends and wherein the dividing line extends from the first attachment point in a first axial direction toward the second end and makes a first turn to travel in a second axial direction toward the first end.

15. An endoluminal prosthesis as in claim 14, wherein the dividing line makes a third turn to travel again in the first axial direction

16. An endoluminal prosthesis as in claim 15, wherein the dividing line makes a fourth turn to travel again in the second axial direction

17. An endoluminal prosthesis as in claim 11, wherein at least some of the turns are 135° or greater.

18. An endoluminal prosthesis as in claim 11, wherein at least some of the turns are 180° or greater.

19. An endoluminal prosthesis as in claim 11, wherein at least some of the turns are greater than 180°.

20. An endoluminal prosthesis as in claim 11, wherein the axially extending dividing line has one or more straight portions joined to one or more curves sections.

21. An endoluminal prosthesis as in claim 21, wherein the axially extending dividing line has a curved region attached to the attachments point on one circumferential ring followed by a straight region followed by a curved region attached to the attachment point on the adjacent circumferential ring.

22. An endoluminal prosthesis as in claim 14, wherein the axially extending dividing line has a curved region attached to the attachments point on one circumferential ring followed by a second curved region having a different direction of curvature that the first region region followed by a third curved region having a different direction of curvature than the second curved region attached to the attachment point on the adjacent circumferential ring.

23. An endoluminal prosthesis as in claim 1, wherein the axially extending dividing line an S-shape.

24. An endoluminal prosthesis as in claim 1, wherein the axially extending dividing line has a W-shape.

25. An endoluminal prosthesis as in claim 1, wherein the axially extending dividing line has a serpentine shape.

26. An endoluminal prosthesis as in claim 1, wherein at least some of the circumferentially separable axial links comprise nested curves with having a male portion and a female portion which engage in an interference fit prior to expansion of the scaffold.

27. An endoluminal prosthesis as in claim 1, wherein at least some of the circumferentially separable axial links comprise nested wedges with having a male portion and a female portion which engage in an interference fit prior to expansion of the scaffold.

28. An endoluminal prosthesis comprising:

configuration, wherein at least some adjacent circumferential rings are joined by circumferentially separable axial links;

said circumferentially separable axial links are divided along the axial joining line into two portions each having one or more corresponding bends, curves, straight areas, angles, or any combination thereof, wherein said portions are configured to fit together and inhibit separation of the portions during expansion of the scaffold, but are configured to separate along said axial joining line following expansion of said scaffold in a physiologic environment, allowing said adjacent circumferential rings joined by said separable axial links to circumferentially open, while said adjacent rings remain axially attached through said portions.

29. An endoluminal prothesis comprising

a scaffold having a plurality of circumferential rings comprising struts and crowns, said rings patterned from a non-degradable material, said scaffold being configured to expand from a crimped configuration to an expanded configuration,

wherein at least some circumferential rings comprise one or more sections of two aligned struts, each strut joined to an adjacent circumferential ring through a link or connector, said two aligned struts held together during expansion of said scaffold but configured to separate after expansion of the scaffold under physiologic conditions.
