First Claim
Patent Images
1. An endoluminal prosthesis comprising:
- a helical scaffold having a multiplicity of adjacent helical turns comprising a plurality of struts joined by crowns, wherein at least some helical turns are axially connected to adjacent helical turns, said scaffold being expandable from a crimped configuration to a deployed configuration;
wherein at least some helical turns include at least one separation region configured to be held together during expansion and to separate after expansion of the scaffold to the deployed configuration 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.
