Complex coil and manufacturing techniques

1. A method of creating a secondary shape of an embolic coil, comprising:

providing a mandrel having an elongated core with an axis extending therealong and a plurality of mounting elements disposed on said elongated core, wherein said plurality of mounting elements each comprise a bracket member having a post member extending generally perpendicular to said axis of said elongated core;

providing an embolic coil;

wrapping said embolic coil on said mandrel so as to create a repeating pattern of loops relative to said axis of said elongated core; said pattern consisting essentially of:

a first horizontal loop positioned at a first angle;

a first vertical loop directly connected to said first horizontal loop and being positioned at a second angle perpendicular to said first angle;

a first angled loop directly connected to said first vertical loop; said first angled loop being oriented at a third angle that is between said first and said second angle; and,

a second vertical loop directly connected to said first angled loop and being positioned at said second angle; and,

heat setting said embolic coil so as to impart said repeating pattern in said mandrel as a secondary shape.

2. The method of claim 1 , wherein said third angle is about 60 degrees relative to said first angle.

3. The method of claim 1 , wherein said repeating pattern further comprises:

a second horizontal loop connected to said second vertical loop and being positioned at said first angle;

a third vertical loop connected to said second horizontal loop and being positioned at said second angle.

4. The method of claim 3 , wherein said repeating pattern further comprises: a second angled loop connected to said third vertical loop and being angled at said third angle.

5. The method of claim 4 , wherein said repeating pattern further comprises: a third horizontal loop connected to said second angled loop and being angled at said second angle.

6. A method of creating a secondary shape of an embolic coil, comprising:

providing an embolic coil;

providing a mandrel having an elongated shape with an axis extending therethrough;

creating one or more of the following pattern, the pattern consisting essentially of:

forming a first horizontal loop with said embolic coil around a first post member that is positioned on said mandrel at a first angle perpendicular to said axis;

forming a first vertical loop that immediately follows said first horizontal loop, with said embolic coil around said axis;

forming a second horizontal loop that immediately follows said first vertical loop, with said embolic coil around a second post member that is positioned on said mandrel at a second angle perpendicular to said axis; said second angle being different from said first angle;

forming a second vertical loop that immediately follows said second horizontal loop, with said embolic coil around said axis; and,

heat setting said embolic coil so as to impart said repeating pattern in said mandrel as a secondary shape.

7. The method of claim 6 , wherein said second angle is positioned at about 60 degrees relative to said first vertical loop.

8. The method of claim 6 , further comprising forming a third horizontal loop with said embolic coil on a third post member that is positioned on said mandrel at said first angle perpendicular to said axis.

9. The method of claim 8 , further comprising forming a third vertical loop with said embolic coil around said axis.

10. The method of claim 9 , further comprising forming a fourth horizontal loop with said embolic coil on a fourth post member that is positioned on said mandrel at said second angle.

11. A method of creating a secondary shape of an embolic coil, comprising:

providing a mandrel having an elongated shape with an axis extending therealong and a plurality of mounting elements disposed along said elongated shape;

providing an embolic coil;

wrapping said embolic coil on said mandrel so as to create a repeating pattern of loops; said pattern consisting essentially of:

a first axially-horizontal loop positioned at a first angle parallel to said axis;

a first vertical loop that immediately follows said first axially-horizontal loop, connected to said first axially-horizontal loop and being positioned around said axis;

a second axially-horizontal loop that immediately follows said first vertical loop, connected to said first vertical loop; said second axially-horizontal loop being oriented at a second angle parallel to said axis; said second angle being different from said first angle; and,

a second vertical loop that immediately follows said second axially-horizontal loop, connected to said second axially-horizontal loop and being positioned around said axis; and,

heat setting said embolic coil so as to impart said repeating pattern in said mandrel as a secondary shape.

12. The method of claim 11 , wherein said mandrel comprises an elongated core with a plurality of brackets mounted thereon, said brackets each having a post extending radially away from said elongated core.
