PROBLEM TO BE SOLVED: To provide a vasculature occlusion device detachment system including a heating element of a predetermined resistivity.SOLUTION: A coil securing suture terminates in a proximal bead retained within the heating element while the distal end of the coil securing suture extends beyond the distal end of the heating element and is attached to the proximal end of the vasculature occlusion device. The coil securing suture is independently rotatable of the heating element 360° about a longitudinal axis extending through the heating element. A power source applies an electrical current to the 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, cut the coil securing suture.SELECTED DRAWING: Figure 1A |
