Abstract
A stent and method of making incorporating flexible, preferably polymeric, connecting elements into the stent wherein these elements connect element(s) across an intervening space. The polymeric connecting elements are designed to fold within the space between the outer diameter of the stent and the inner diameter of the stent.
Claims20
An endoprosthesis having a length, a radius, an inner circumference and an outer circumference, the endoprosthesis comprising:
- adjacent stent elements formed of a first material;
- and
- a flexible connecting element formed of a second material different than the first material, the second material being a polymeric material and the flexible connecting element spanning across a space between adjacent stent elements;
- and
- wherein the flexible connecting element is biased to fold substantially between the inner circumference and the outer circumference of the endoprosthesis when the endoprosthesis is compacted.

An endoprosthesis having a length, a radius, an inner circumference and an outer circumference, the endoprosthesis comprising:
- adjacent stent elements formed of a first material;
- a flexible connecting element formed of a second material, the second material being a polymeric material, the flexible connecting element spanning across a space between adjacent stent elements;
- and
- wherein the flexible connecting element has a section modulus (Mr) in a direction aligned with the radius of the endoprosthesis and a section modulus (Mp) aligned in a direction perpendicular to the radius of the endoprosthesis, wherein Mr/Mp of the flexible connecting element is configured such that the flexible connecting element is configured to fold substantially within the inner circumference and the outer circumference of the endoprosthesis when the endoprosthesis is compacted longitudinally.
