| Claim: | 1. A flat metallic wire ribbon in the shape of an embolic coil, the ribbon having a first side with a first thickness and a second side with a second thickness different from the first thickness wherein consecutive windings are flush with one another. |
| Claim: | 2. The ribbon of claim 1 , wherein the first thickness is larger than the second thickness, and the first side faces the outside of the embolic coil. |
| Claim: | 3. The ribbon of claim 1 , wherein the first thickness is larger than the second thickness and the second side faces the outside of the embolic coil. |
| Claim: | 4. The ribbon of claim 1 further comprising at least one fiber disposed between at least two windings of the ribbon. |
| Claim: | 5. The ribbon of claim 1 , wherein the ribbon forms a first shape that is a substantially spiral shape characterized by an outer diameter and a second shape characterized by a maximal cross-sectional dimension in an unconstrained state that is greater than the outer diameter of the first shape. |
| Claim: | 6. The ribbon of claim 1 , wherein the shape is selected from the group consisting of a spiral, a single apex vortex, a dual apex vortex, a J, and a complex helical shape. |
| Claim: | 7. An embolic coil, comprising: a first outer region comprising a plurality of windings, the first region characterized by a first outer diameter; and a second region comprising a plurality of windings, the second region characterized by a second outer diameter different from the first outer diameter. |
| Claim: | 8. The embolic coil of claim 7 , wherein each of the first and second regions are formed by a plurality of windings of a wire. |
| Claim: | 9. The embolic coil of claim 7 , wherein at least one of the first and second regions repeats over a length of the embolic coil. |
| Claim: | 10. The embolic coil of claim 7 , wherein at least one of the first and second regions further comprises at least one fiber disposed between at least two windings of a ribbon. |
| Claim: | 11. The embolic coil of claim 7 , wherein the embolic coil is formed from a flat metallic wire ribbon having a first side with a first thickness and a second side with a second thickness different from the first thickness. |
| Claim: | 12. A flat metallic wire ribbon in the shape of an embolic coil, the ribbon having a first side with a first thickness and a second side with a second thickness different from the first thickness wherein the embolic coil has a pitch equal to the first thickness of said ribbon. |
