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.

Claims

1. An apparatus for treating vascular aneurysms, comprising:

a support member; 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 comprise 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 tangential width.

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

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

10. The apparatus of claim 1, wherein a tangential thickness of said portion of said support member and said reactive fiber strand is substantially the same as the remaining portion of said support member.

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 shape and sized for delivery within a 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 sized for delivery within a 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.
