1. A method of making an embolic device, the method comprising:

  • collapsing a midsection of a tubular braid to a substantially closed configuration using a tie;

    inverting a first tubular section of the tubular braid over the tie at the midsection to produce dual layers in the braid such that the braid has a tubular configuration with a closed end at the midsection and an open end opposite the midsection;

    while holding the midsection substantially closed, inserting a form into the open end to position the dual layers of the braid around the form;

    setting a device body shape; and

    removing the tie and the form from the braid, the form being removed in one piece.
