Claims
- 1. A vasoocclusive device adapted, sized, and configured for introduction into a vascular lumen consisting essentially of:
- a. a helical coil having a multiplicity of windings and having a first end and a second end, a passageway between the first end and second end, and
- b. at least one fibrous woven tubular member extending coaxially about at least a portion of the helical coil and adhering to the helical coil at least one location on the coil
- where the device is of a diameter which may be introduced through the lumen of a vascular catheter and of a diameter which is smaller than the diameter of the vascular lumen.
- 2. The device of claim 1 in which the helical coil is segmented.
- 3. The device of claim 2 in which the fibrous woven tubular member is braided.
- 4. The device of claim 3 in which the fibrous woven tubular member has an inside and an outside and wherein the device additionally comprises tassels extending beyond the outside of said tubular member.
- 5. The device of claim 1 in which the helical coil is continuous.
- 6. The device of claim 1 in which the fibrous at least one woven tubular member is braided.
- 7. The device of claim 6 in which the fibrous at least woven tubular member has an inside and an outside and wherein the device additionally comprises tassels extending beyond the outside of said tubular member.
- 8. The device of claim 6 where the helical coil assumes a random configuration when utilized.
- 9. The device of claim 6 when the helical coil assumes a cloverleaf configuration where relaxed.
- 10. The device at claim 6 where the helical coil assumes a regular coiled configuration where relaxed.
- 11. The device of claim 6 where the helical coil assumes a coiled shape having two secondary diameters where relaxed.
- 12. The device of claim 1 including multiple fibrous woven tubular members.
- 13. The device of claim 12 where the tubular members have a first end and a second end.
- 14. The device of claim 13 where the tubular member first ends are attached to the helical coil.
- 15. The device of claim 14 where the tubular member second ends are also attached to the helical coil.
- 16. The device of claim 15 where the tubular members are axially compressed on the axis between their first and second ends and bulge from the coil.
- 17. The device of claim 1 where the helical coil has a diameter of 0.008 to 0.018 inches.
