Abstract
Luminal prostheses comprise adjacent expansible segments, typically serpentine ring segments joined by sigmoidal links. By properly orienting the sigmoidal links and aligning hinge regions on adjacent serpentine rings, enhanced opening characteristics can be obtained. Additionally, by varying the mechanical characteristics of adjacent serpentine rings, program expansion of the luminal prostheses over their lengths may be obtained. The disclosed prostheses also have controllable opening characteristics and can be crimped to small diameters.
