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.
Claims30
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 at least some of the circumferential rings have at least one separation region configured to form at least one discontinuity in said circumferential rings after expansion in a physiologic environment and at least portions of two of the circumferential rings remain axially joined after all discontinuities are formed.
