Abstract
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 having a boundary layer 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-flexible materials, shape memory materials, and/or radiopaque materials.
Claims15
A crack-resistant endoprosthesis comprising:
- a first layer of a first material;
- and
- a second layer of a second material adjacent to the first layer at a boundary region thereby forming a boundary layer, wherein the boundary layer is configured to inhibit a crack from propagating between the first and second layers.
A crack-resistant endoprosthesis comprising:
- a first layer comprised of a first material;
- and
- a second layer comprised of a second material bound to the first layer at a boundary region, wherein the boundary region is configured to inhibit a crack from propagation between the first and second layers.
