VISIBLE ENDOPROSTHESIS

摘要

A crack- resistant endoprosthesis for delivery in a body lumen can be comprised of a multilayered material. The multilayered material can include at least two layers (212a, 212b) having a boundary layer (214a) therebetween. The boundary layer is configured to inhibit cracks from propagating from a first layer to a second layer. The different layers can be comprised of the same materials or different materials. It can be preferred that the multilayered material have layers that are comprised of resiliently-f lexible materials, shape memory materials, and/or radiopaque materials.
