Abstract
The winding mandrel includes a pair of generally rounded-cube shaped or orthogonally flat-sided spherical main bodies connected together and having a plurality of cylindrical posts for forming vasoocclusive coils. The main bodies are connected together by a transition post, and the posts of the two main bodies are typically offset. A front end post and back end post are disposed on the front and rear ends of the mandrel. A short winding post member may be added between the connections of the two main bodies to provide additional winding posts.
Claims7
A winding mandrel for forming at least a portion of a vasoocclusive coil, comprising:
- first and second spherical main bodies each having a plurality of flat sides, each of said first and second spherical main bodies having a plurality of cylindrical posts disposed on the first and second spherical main bodies, the plurality of cylindrical posts disposed on the first main body being aligned with orthogonal x and y axes through the first main body, and the plurality of cylindrical posts disposed on the second main body being aligned with orthogonal x and y axes through the second main body, wherein said first and second spherical main bodies are configured to be angularly offset with respect to each other;
- a central transition post extending between and connecting said first and second main bodies:
- at least one central cylindrical winding post connected to and extending perpendicularly from said central transition post;
- a front end cylindrical post disposed on one of said first and second spherical main bodies;
- and
- a back end cylindrical post disposed on the other of said first and second spherical main bodies.
