1. A vasculature occlusion device detachment system comprising:

  • a wound coil heating element of a predetermined resistivity;

    the wound coil heating element having a proximal end and an opposite distal end;

    a coil securing suture having a distal end and an opposite proximal end;

    the proximal end of the coil securing suture terminating in a proximal bead retained within the wound coil heating element while the distal end of the coil securing suture extends beyond the distal end of the wound coil heating element;

    the coil securing suture being rotatable, independently of the wound coil heating element, 360 degrees about a longitudinal axis extending therethrough the wound coil heating element;

    an electrically conductive corewire having a proximal end and an opposite distal end;

    the distal end of the electrically conductive corewire being connected to the proximal end of the wound coil heating element; and

    an insulated electrically conductive wire separate from the electrically conductive corewire;

    the insulated electrically conductive wire having a proximal end and an opposite distal end;

    the distal end of the insulated electrically conductive wire being secured to the wound coil heating element at a wound coil heating element to conductive wire connection.
