The device of claim 10, wherein the anchor bulb has a porosity configured to decrease flow into an aneurysm. 14. The device of claim 10, wherein the at least one of the first neck, the second neck, and the third neck is on a different plane than the others of the first neck, the second neck, and the third neck. 15. The device of claim 10, wherein the second neck has a first length and the third neck has a second length less than the first length. 16. A device for treating a vessel, the device comprising: a plurality of wires forming a textile structure transformable between a radially compressed state and a radially expanded state,the textile structure comprising, in the radially expanded state: an first bulb having a first braid angle,a first neck extending from the first bulb,a second neck extending from the first bulb, the second neck having a second braid angle less than the first braid angle, anda third neck extending from the first bulb, the second neck having a third braid angle less than the first braid angle. 17. The device of claim 16, wherein the first neck comprises a second bulb. 18. The device of claim 17, wherein each of the first bulb and the second bulb has a porosity configured to decrease flow into an aneurysm. 19. The device of claim 16, wherein the first bulb has a porosity configured to decrease flow into an aneurysm. 20. The device of claim 16, wherein the first neck has a first length, the second neck has a second length less than the first length, and the third neck has a third length less than the second length, and wherein the at least one of the first neck, the second neck, and the third neck is on a different plane than the others of the first neck, the second neck, and the third neck.
