1. A method of manufacturing a vascular treatment device, the method comprising: arranging a plurality of spools on spindles on a yarn wheel, at least some of the spools comprising radiopaque wires and at least some of the spools comprising shape memory wires;attaching an end of each of the wires to
1. A method of manufacturing a vascular treatment device, the method comprising: arranging a plurality of spools on spindles on a yarn wheel, at least some of the spools comprising radiopaque wires and at least some of the spools comprising shape memory wires;attaching an end of each of the wires to a ring over a first mandrel, the first mandrel comprising a substantially cylindrical shape;braiding the radiopaque wires and the shape memory wires in a one-over-one-under-one pattern around the first mandrel to form a textile structure, wherein braiding comprises rotating the yarn wheel, rotating the spindles, and longitudinally pulling the ring along the first mandrel away from the yarn wheel;shape setting the textile structure into a substantially cylindrical shape;securing the shape-set textile structure on a second mandrel comprising bulbs and necks, wherein the second mandrel comprises bulbs threaded along a strand;shape setting the shape-set textile structure on the second mandrel; andremoving the shape-set textile structure from the second mandrel. 2. The method of claim 1, wherein securing the shape-set textile structure on the second mandrel comprises wrapping a wire around the necks of the second mandrel. 3. The method of claim 1, further comprising forming the second mandrel. 4. The method of claim 3, wherein forming the second mandrel comprises stringing the bulbs along the strand. 5. The method of claim 4, wherein stringing the bulbs along the strand comprises selecting shapes of the bulbs, sizes of the bulbs, and spacing between the bulbs. 6. The method of claim 1, wherein arranging the plurality of spools comprises positioning at least two of the spools comprising radiopaque wires adjacent to each other. 7. The method of claim 1, further comprising bonding the shape-set textile structure to a hypotube. 8. A method of manufacturing a vascular treatment device, the method comprising: arranging a plurality of spools of wire on spindles on a yarn wheel;braiding the wires around a mandrel comprising bulbs and necks to form a textile structure, wherein the mandrel comprises bulbs threaded along a strand, and wherein braiding comprises pulling a ring attached to an end of each of the wires away from the yarn wheel;shape setting the textile structure on the mandrel; andremoving the shape-set textile structure from the mandrel. 9. The method of claim 8, further comprising securing the textile structure on the mandrel before shape setting. 10. The method of claim 8, further comprising forming the mandrel. 11. The method of claim 10, wherein forming the mandrel comprises stringing the bulbs along the strand. 12. The method of claim 11, wherein stringing the bulbs along the strand comprises selecting shapes of the bulbs, sizes of the bulbs, and spacing between the bulbs. 13. The method of claim 8, further comprising bonding the shape-set textile structure to a hypotube. 14. The method of claim 1, wherein the textile structure comprises two sine waves each comprising a radiopaque wire, the two sine waves phase shifted from each other by about 180°. 15. The method of claim 1, wherein the textile structure comprises three sine waves each comprising a radiopaque wire, the three sine waves phase shifted from each other by about 120°. 16. The method of claim 1, wherein the textile structure comprises a first sine wave comprising a radiopaque wire, a second sine wave comprising a radiopaque wire, the second sine wave phase shifted from the first sine wave by about 180°, a third sine wave comprising a radiopaque wire, the third sine wave phase shifted from the first sine wave by about 7.5°, and a fourth sine wave comprising a radiopaque wire, the fourth sine wave phase shifted from the third sine wave by about 7.5°. 17. The method of claim 1, wherein securing the shape-set textile structure on the second mandrel comprises wrapping bangles around the necks of the second mandrel. 18. The method of claim 1, wherein securing the shape-set textile structure on the second mandrel comprises wrapping c-shaped clamps around the necks of the second mandrel. 19. The method of claim 8, wherein securing the shape-set textile structure on the second mandrel comprises wrapping a wire around the necks of the second mandrel. 20. The method of claim 8, wherein securing the shape-set textile structure on the second mandrel comprises wrapping bangles around the necks of the second mandrel. 21. The method of claim 8, wherein securing the shape-set textile structure on the second mandrel comprises wrapping c-shaped clamps around the necks of the second mandrel.
