A vasculature occlusion device detachment system including a wound coil heating element of a predetermined resistivity. A coil securing suture terminates 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 and is attached to the proximal end of the vasculature occlusion device. The coil securing suture is independently rotatable of the wound coil heating element 360 degrees about a longitudinal axis extending therethrough the wound coil heating element. A power source applies electrical current to the wound coil heating element via an electrically conductive corewire and separate insulated electrically conductive wire to increase its resistance and, as a result of the heat produced, sever the coil securing suture.
