1. An endoluminal prosthesis comprising:
- a scaffold comprising a plurality of axially adjacent circumferential rings, said scaffold being configured to expand from a crimped configuration to an expanded configuration;
wherein at least one first element from a first ring is joined to a second element from an adjacent second ring, wherein an end of a third element from the first ring is detachably attached to said second ring, wherein the first element from the said first ring and second element from the said second ring are configured to remain attached after the third element detaches, and wherein each said detachment of the third element provides a separation of the third element from said second ring and provides a discontinuity in the circumferential path of the first circumferential ring, and wherein said third element is configured to detach after expansion of said scaffold in a physiologic environment.

Abstract
A stent (scaffold) or other luminal prosthesis comprising circumferential structural elements which provides high strength after deployment and allows for scaffold to uncage, and/or allow for scaffold or luminal expansion thereafter. The circumferential scaffold may be formed from degradable material, or may be formed from non-degradable material and will be modified to expand and/or uncage after deployment.

19. An endoluminal prosthesis comprising:
-
a scaffold comprising a plurality of axially adjacent circumferential rings, said scaffold being configured to expand from a crimped configuration to an expanded configuration; wherein at least some axially adjacent first and second circumferential rings comprise elements joining said adjacent rings and forming a junction, wherein an end of one element of said first circumferential ring is detachably attached at said junction and other elements of said junction are configured to remain joined after the one element detaches, wherein said detachable element is configured to detach after expansion of the scaffold in a physiologic environment and, wherein each said one element detachment provides a separation of said one element from said second adjacent ring and provides a discontinuity in a circumferential path of the first circumferential ring. - View Dependent Claims (21, 22, 23, 24, 26, 27, 28, 32, 33, 34)
