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.
Claims18
An endoprosthesis having a length, a radius, and a circumference, the endoprosthesis comprising;
- a stent formed by a plurality of windings, the plurality of windings having multiple apices;
- a first film web coupled to two adjacent windings and exhibiting a first stiffness;
- and
- a second film web coupled to two adjacent windings and exhibiting a second stiffness greater than the first stiffness, the second film web covering a straight segment of a winding between adjacent apices of the winding.
An endoprosthesis having a length, a radius, and a circumference, the endoprosthesis comprising;
- a stent having a plurality of stent elements forming a serpentine pattern with multiple apices;
- and
- a first film web attaching a first stent element to a second stent element and a second film web, attaching adjacent stent elements, of the plurality of stent elements the first film web including a web reinforcement, the second film web covering a straight segment of the serpentine pattern between adjacent apices of the serpentine pattern.
An endoprosthesis having a length, a radius, and a circumference, the endoprosthesis comprising;
- a stent formed by a plurality of windings, the plurality of windings having multiple apices and including a first winding adjacent to a second winding;
- and
- a film web including a first portion coupled between the first winding and the second winding and a second portion separate and distinct from the first portion and coupled between the first winding and the second winding, the film web covering straight segments of the plurality of windings.
