Abstract

The present application discloses an apparatus for treating vascular aneurysms and includes a radially expandable substantially cylindrical structure formed from a plurality of support members and defining a plurality of openings, and at least one reactive material strand selectively integrated into the substantially cylindrical structure. The reactive material is configured to assume a non-reacted state and a reacted state. The reactive material in the reacted state is configured to restrict a flow of blood to an aneurysm.

First claim

What is claimed is:

1. An apparatus for treating vascular aneurysms, comprising:
a support member forming a stent that is radially expandable to a diameter of a blood vessel; and,
a reactive fiber strand encircling a portion of said support member.

2. The apparatus of claim 1 , wherein said reactive fiber strand comprises a reactive material having a reacted state that increases resistance to the flow of blood to an aneurysm.

3. The apparatus of claim 1 , wherein said reactive fiber strand comprises a hydrogel that volumetrically expands over time within the presence of blood.

4. The apparatus of claim 1 , wherein said reactive fiber strand is adhesively coupled to the support member.

5. The apparatus of claim 1 , wherein said support member has a constant diameter.

6. The apparatus of claim 1 , wherein said support member has a variable diameter.

7. The apparatus of claim 1 , wherein said support member has a variable width.

8. The apparatus of claim 1 , wherein said support member has a region of reduced width and wherein said reactive fiber strand is wrapped around said region of reduced width.

9. The apparatus of claim 8 , wherein a width of said region of reduced width and said reactive fiber strand is substantially the same as a second portion of said support member adjacent to said region of reduced width.

10. The apparatus of claim 1 , wherein a thickness of said portion of said support member and said reactive fiber strand is substantially the same as a second portion of said support member adjacent to said region of reduced width.

11. The apparatus of claim 1 , wherein said reactive fiber strand is wound so as to form gaps between each of its windings.

12. The apparatus of claim 1 , wherein said reactive fiber strand further comprises a core member of non-expansible material.

13. The apparatus of claim 1 , wherein a reactive material of said reactive fiber strand comprises a compound to promote tissue growth.

14. The apparatus of claim 1 , wherein said support member comprises a compound to promote tissue growth.

15. The apparatus of claim 1 , wherein said support member forms a zig-zag shape.

16. The apparatus of claim 1 , wherein said support member defines a shape having an internal passage.

17. The apparatus of claim 1 , further comprising a plurality of support members, wherein said reactive fiber strand is selectively wrapped around each of said plurality of support members.

18. The apparatus of claim 1 , wherein said reactive fiber strand has a thickness between about 10% and 200% of the largest thickness of said support member.

19. An apparatus for treating vascular aneurysms, comprising:
a support member forming an aneurysm treatment stent that is sized for delivery within a blood vessel and expandable to a diameter of said blood vessel; and,
a reactive fiber strand wound around at least a portion of said support member.

20. A method of creating a vascular treatment apparatus for aneurysms, comprising:
providing a support member forming a stent sized for delivery within a human blood vessel and being expandable to a diameter of said human blood vessel;
winding a reactive fiber strand around at least a portion of said support member.

21. The method of claim 20 , wherein said winding said reactive fiber strand further comprises winding said reactive fiber strand around a reduced diameter region of said support member.

22. The method of claim 20 , wherein said reactive fiber strand comprise a hydrogel that volumetrically expands over time within the presence of blood.

23. The method of claim 20 , wherein said reactive fiber strand is adhesively coupled to said support member.
