Abstract

A multiple-sided medical device comprises a closed frame of a single piece of wire or other resilient material and having a series of bends and interconnecting sides. The device has both a flat configuration and a second, folded configuration that comprises a self-expanding stent. The stent is pushed from a delivery catheter into the lumen of a duct or vessel. One or more barbs are attached to the frame of the device for anchoring or to connect additional frames. A covering of fabric or other flexible material such as DACRON, PTFE, or collagen, is sutured or attached to the frame to form an occlusion device, a stent graft, or an artificial valve such as for correcting incompetent veins in the lower legs and feet. A partial, triangular-shaped covering over the lumen of the device allows the valve to open with normal blood flow and close to retrograde flow.

Claims

1. A multiple-sided intraluminal medical device comprising:

a first end and a second end;

a frame having a first and a second configuration and closed circumference with an aperture therethrough, said closed circumference having a plurality of sides and a plurality of bends interconnecting said plurality of sides, said plurality of bonds in said first configuration comprising at least a first pair of opposite bends and a second pair of opposite bends;

wherein said frame in said second configuration is folded on at least a diagonal axis across said aperture of said frame, bringing said first pair of opposite bends in closer proximity at said first end of said device and said second pair of opposite bends in closer proximity at second end of said device.

2. The device of claim 1, further including a covering attached to said plurality of sides.

3. The device of claim 2, wherein said covering includes an opening therethrough.

4. The device of claim 2, wherein said covering is attached to at least two of said plurality of sides.

5. The device of claim 4, wherein said covering is attached to each of said plurality sides.

6. The device of claim 5, wherein said covering includes an opening therethrough.

7. The device of claim 1, wherein said frame includes four sides and four interconnecting bends.

8. The device of claim 1, wherein at least said first pair of opposite bends are disposed on a diagonal axis across said aperture of said frame.

9. The device of claim 1, wherein said device with said frame in said second configuration includes a generally circular appearance when viewed from at least one of said first and said second ends.

10. A multiple-sided intraluminal medical device comprising:

a first end and a second end;

a frame having a first and a second configuration and closed circumference with an aperture therethrough, said closed circumference having a plurality of sides and a plurality of bends interconnecting said plurality of sides, said plurality of bends in said first configuration comprising at least a first pair of non-adjacent bends and a second pair of non-adjacent bends;

wherein said frame in said second configuration is folded on at least a diagonal axis across said aperture of said frame, bringing said first pair of non-adjacent bends in closer proximity at said first end of said device and said second pair of non-adjacent bends in closer proximity at second end of said device.

11. The device of claim 10, further including a covering attached to said plurality of sides.

12. The device of claim 11, wherein said covering includes an opening therethrough.

13. The device of claim 10, wherein a covering is attached to at least two of said plurality of sides.

14. The device of claim 10, wherein a covering is attached to each of said plurality sides.

15. The device of claim 14, wherein said covering includes an opening therethough.

16. The device of claim 10, wherein said frame includes four sides and four interconnecting bends.

17. The device of claim 10, wherein said device with said frame in said second configuration includes a generally circular appearance when viewed from at least one of said first and said second ends.

18. A multiple-sided intraluminal medical device comprising:

a frame being of a generally polygonal shape with a closed circumference and an aperture therethrough, said closed circumference having a plurality of sides and a series of interconnecting bends, and

a covering attached to said frame and extending across the aperture thereof;

wherein said frame is resiliently foldable across a diagonal axis of said aperture of said frame into a self-expanding stent configuration in which the covering forms a curved configuration adapted to trap fluid flowing in a single direction within a vessel.

19. The device of claim 18 wherein said covering is adapted to restrict fluid flow within the aperture of the frame.

20. The device of claim 18 wherein said covering includes an opening therethrough.

21. The device of claim 18 wherein said covering comprises small intestinal submucosa.
