1. A vasoocclusive device that is adapted to be inserted into a portion of a vasculature for occluding a portion of the vasculature for use in interventional therapy and vascular surgery, comprising:

  • at least one strand of a flexible material formed to have a first portion with a first inoperable, substantially linear configuration for insertion into and through a catheter to a desired portion of the vasculature to be treated, and a second operable, three dimensional substantially box shaped orthogonal configuration for occluding the desired part of the vasculature to be treated; and

    a a second portion extending outwardly from the first portion in its second configuration and having a first inoperable, substantially linear configuration for insertion into and through a catheter to a desired portion of the vasculature to be treated, and a second operable, substantially J-shape for filling and reinforcing the three dimensional shaped portion when the vasoocclusive device is implanted at the site in the vasculature to be treated.
