3. The intraluminal device of claim 1 , wherein the elongated structure is formed of at least 12 wires, and wherein each of the plurality of sets of looped wires is formed of the same at least 12 wires as the at least one grouping of woven wires.

4. The intraluminal device of claim 1 , wherein the structure is formed of 12 wires that, in the intermediate area, define six sets of looped wires, and wherein in the adjacent area, the 12 wires collectively form the at least one grouping of woven wires.

5. The intraluminal device of claim 4 , wherein each of the 12 wires has a diameter of about 80 microns.

6. The intraluminal device of claim 5 , wherein each of the 12 wires has a diameter of 75 microns.

7. An intraluminal device including an elongated structure formed of a plurality of wires, the intraluminal device comprising:

a first region wherein the plurality of wires are twisted to form a shaft;

a second region, adjacent to the first region, wherein the plurality of wires are woven to form a scaffold;

a third region, adjacent to the second region, wherein the plurality of wires are separated into sets of looped pairs to form a clot capture structure, the sets of looped pairs being configured to cross each other at a plurality of intersection locations; and

a fourth region wherein the plurality of wires are braided to form a dense filter configured to catch a blood clot.

8. The intraluminal device of claim 7 , wherein the elongated structure is configured to transition between a collapsed position for delivery to a treatment site, and an expanded position in response to an opening force exerted thereon.

9. The intraluminal device of claim 8 , wherein the elongated structure is configured such that when the opening force is applied, first interstices are formed between wires in the second region, and second interstices are formed between wires in the third region, such that the second interstices are larger than the first interstices.

10. The intraluminal device of claim 9 , wherein the elongated structure is configured such that when the opening force is applied, third interstices are formed between wires in the fourth region, such that the third interstices are smaller than both the first interstices and the second interstices.

11. The intraluminal device of claim 8 , wherein the elongated structure is configured such that the opening force is applied through axial movement of the first region.

12. The intraluminal device of claim 7 , further comprising a fifth region, adjacent to the fourth region, and wherein the plurality of wires in the fifth region are twisted to form an additional shaft.

13. The intraluminal device of claim 7 , wherein the plurality of wires includes 12 wires.

14. The intraluminal device of claim 13 , wherein each of the 12 wires has a diameter of about 80 microns.

15. The intraluminal device of claim 14 , wherein each of the 12 wires has a diameter of 75 microns.

16. The intraluminal device of claim 7 , further comprising an additional second region of scaffold between the third region and the fourth region.

17. An intraluminal device including an elongated structure formed of a plurality of wires, the device comprising:

a plurality of cables each formed of a subset of the plurality of wires, wherein pairs of cables cross each other at a plurality of intersection locations;

wherein at the plurality of intersection locations, wires from each pair of crossing cables are unwound and woven together with wires from a paired crossing cable;

wherein the wires of the crossing cables are woven together at the intersection locations in a manner permitting the woven-together wires to move relative to each other when an opening force is applied to the elongated structure; and

wherein in response to the opening force exerted thereon, at the intersection locations, pairs of crossing cables are configured to pivot relative to each other as the elongated structure transitions between a collapsed position for delivery to a treatment site, and an expanded clot capture position.
