Abstract

Claims (12)

1. A vaso-occlusive device, comprising:

a member that forms a series of at least four successive loops, each loop of the series having a different axis than, and lying in a separate plane from, any other loop of the series, and at least two non-successive loops lying in respective planes which are substantially parallel, each of the four successive loops comprising a helical form having 0.5 to 3.5 rotations about its axis; and

each plane forming an angle greater than 30 degrees with any immediately proceeding and any immediately succeeding plane.

2. The vaso-occlusive device of claim 1 , each plane forming an angle between 45 and 90 degrees with the immediately proceeding and the immediately succeeding plane.

3. The vaso-occlusive device of claim 1 , each plane perpendicular to the immediately proceeding and the immediately succeeding plane.

4. The vaso-occlusive device of claim 1 , wherein the loops are wound in a clockwise direction.

5. The vaso-occlusive device of claim 1 , wherein the loops are wound in a counterclockwise direction.

6. The vaso-occlusive device of claim 1 , wherein at least one of the loops is wound in a clockwise direction, and at least one of the loops is wound in a counterclockwise direction.

7. The vaso-occlusive device of claim 1 , at least one loop comprising an elliptical form.

8. The vaso-occlusive device of claim 1 , at least one loop comprising an oval form.

9. The vaso-occlusive device of claim 1 , at least one of the loops having a different geometric form than the other loops.

10. The vaso-occlusive device of claim 1 , a distal most loop of the series having a diameter smaller than a diameter of an immediately preceding loop.
