An embolic coil including a wire having a primary shape when extended in a lumen of a deployment device, the primary shape with a plurality of first regions each having a first outer diameter, each of the first outer diameters being substantially the same, and a plurality of second regions each h
1. An embolic coil including a wire having a primary shape when extended in a lumen of a deployment device, the primary shape with a plurality of first regions each having a first outer diameter, each of the first outer diameters being substantially the same, and a plurality of second regions each having a second outer diameter that is smaller than the first outer diameter, each of the second outer diameters being substantially the same, wherein: the embolic coil is configured to fit within a lumen of a subject;at least one of the plurality of second regions is located between two of the plurality of first regions; andat least one of the first regions comprises multiple windings with adjacent windings being flush with each other. 2. The embolic coil of claim 1, wherein the first outer diameter is at most about 0.03 inch. 3. The embolic coil of claim 1, wherein the second outer diameter is at most about 0.025 inch. 4. The embolic coil of claim 1, wherein a difference between the first outer diameter and the second outer diameter is at most about 0.024 inch. 5. The embolic coil of claim 1, wherein a ratio of the first outer diameter to the second outer diameter is at least about 1.05:1. 6. The embolic coil of claim 1, further comprising at least one fiber attached to the wire. 7. The embolic coil of claim 6, wherein the at least one fiber is attached to a region of the wire having the second outer diameter. 8. The embolic coil of claim 6, wherein the at least one fiber comprises polyethylene terephthalate or nylon. 9. The embolic coil of claim 6, wherein the at least one fiber has a length of from about 0.5 millimeter to about five millimeters. 10. The embolic coil of claim 1, wherein the embolic coil has an effective column strength of from 0.005 pound to about 0.05 pound. 11. The embolic coil of claim 1, wherein the wire has a diameter of from 0.001 inch to 0.005 inch. 12. The embolic coil of claim 1, wherein the wire comprises a metal. 13. The embolic coil of claim 1, wherein the wire has a secondary shape that is a J, a diamond, a vortex, or a spiral. 14. The embolic coil of claim 1, wherein the plurality of first regions and the plurality of second regions are arranged in an alternating sequence. 15. The embolic coil of claim 1, wherein the embolic coil has a pitch that is at most 0.003 inch. 16. The embolic coil of claim 1, wherein the embolic coil has a pitch of at most 0.01 inch. 17. The embolic coil of claim 16, wherein the plurality of first regions and the plurality of second regions are arranged in an alternating sequence. 18. The embolic coil of claim 17, the wire has a secondary shape that is a J. 19. The embolic coil of claim 17, the wire has a secondary shape that is a diamond, a vortex, or a spiral. 20. The embolic coil of claim 17, wherein the wire has a diameter of from 0.001 inch to 0.005 inch. 21. The embolic coil of claim 17, wherein the plurality of first regions and the plurality of second regions are arranged in an alternating sequence. 22. The embolic coil of claim 17, wherein the first outer diameter is at most about 0.03 inch. 23. The embolic coil of claim 22, wherein the second outer diameter is at most about 0.025 inch. 24. The embolic coil of claim 17, wherein a difference between the first outer diameter and the second outer diameter is at most about 0.024 inch. 25. The embolic coil of claim 17, wherein a ratio of the first outer diameter to the second outer diameter is at least about 1.05:1. 26. The embolic coil of claim 1, wherein the at least one of the second regions comprises multiple windings with adjacent windings being flush with each other. 27. A medical device, comprising: a tubular body defining a lumen; andat least one embolic coil disposed within the lumen, the at least one embolic coil including a wire having a primary shape when extended in the lumen, the primary shape with a plurality of first regions each having a first outer diameter, each of the first outer diameters being substantially the same, and a plurality of second regions each having a second outer diameter that is smaller than the first outer diameter, each of the second outer diameters being substantially the same;wherein at least one of the plurality of second regions is located between two of the plurality of first regions, and at least one of the first regions comprises multiple windings with adjacent windings being flush with each other. 28. The medical device of claim 27, wherein the at least one embolic coil comprises multiple embolic coils. 29. The medical device of claim 27, further comprising a pusher wire. 30. The medical device of claim 29, wherein the pusher wire is disposed within the lumen of the tubular body and attached to the embolic coil. 31. The medical device of claim 27, wherein the tubular body comprises a catheter.
