Abstract

A covered stent comprises a coiled sheet stent (12) having at least a portion with open cell geometry (31) and a graft material (30) covering at least a portion of the coiled sheet stent.

Claims (28)

1. A covered stent comprising:
a coiled sheet stent having an expandable cell geometry and a graft material covering at least a portion of the coiled sheet stent.
2. The covered stent of claim 1, wherein the graft material covers the entire coiled sheet stent.
3. The covered stent of claim 1, wherein the stent is configured with at least a portion with an open cell geometry.
4. The covered stent of claim 1, wherein the graft material is located on only one side of the coiled sheet stent.
5. The covered stent of claim 1, wherein the graft material entirely covers only one side of the coiled sheet stent.
6. The covered stent of claim 1, wherein the graft material is located on an interior side and an exterior side of the coiled sheet stent.
7. The covered stent of claim 6, wherein the graft material entirely covers the interior side of the coiled sheet stent and less than the entirety of the exterior side of the coiled sheet stent.
8. The covered stent of claim 6, wherein the graft material entirely covers an exterior side of the coiled sheet stent and less than the entirety of the interior side of the coiled sheet stent.
9. The covered stent of claim 1, wherein the graft material covers a portion of one side of the coiled sheet stent and folds over a portion of a second side of the coiled sheet stent.
10. The covered stent of claim 1, wherein the graft material is tubular and the stent is placed inside the graft material such that a portion of a first and a portion of a second side are covered.
11. The covered stent of claim 1, wherein the graft material covers only portions of the stent that have open cell geometries.
12. The covered stent of claim 1, wherein the graft material covers portions of the stent that have closed cell geometries.
13. The covered stent of claim 1, wherein the graft material covers portions of the stent having open cell geometries and portions of the stent having closed cell geometries.
14. The covered stent of claim 1, wherein there is a plurality of layers with graft material between multiple layers.
15. The covered stent of claim 14, wherein the graft material is constructed of MRI
compatible material.
16. The covered stent of claim 14 wherein the graft material acts as an electrical insulator between conductive layers of the stent.
17. The covered stent of claim 1, having the graft material between cells which are radially adjacent.
18. The covered stent of claim 1, wherein at least one of the radial cells are open cells.
19. The covered stent of claim 1, wherein the graft material covers at least one cell having one or more unconnected peaks.
20. The covered stent of claim 19 covering a plurality of cells having unconnected peaks.
21. The covered stent of claim 1, wherein the stent delivers a drug of medicinal value.
22. The covered stent of claim 21, wherein the drug is coated on the stent.
23. The covered stent of claim 21, wherein the drug is contained in the stent.
24. The covered stent of claim 1, wherein the graft material delivers a drug.
25. The covered stent of claim 24, wherein the drug is coated on the graft material.
26. The covered stent of claim 24, wherein the drug is contained in the graft material.
27. A method of preventing radially adjacent cells of a coil stent from intertangling comprising the steps of:
1) providing a stent with a plurality of cells 2) disposing a graft material over at least some of the cells so that at least some cells which are radially adjacent one another are separated by the graft material.
28. The method of claim 27 wherein at least one of the radially adjacent cells has an open cell geometry.
