1. A vascular occlusion device deployment system, comprising: a vascular occlusion device having a protruding portion; a deployment unit comprising a pusher having a proximal end portion and a distal end portion; an expandable gripper located at the distal end portion of the pusher, said gripper including an outwardly expandable gripping element for gripping the protruding portion of the vascular occlusion device; a dispensing tube adapted to accommodate a first reactant separate from a second reactant; an expandable reaction chamber located within said gripper, said expandable reaction chamber having an expandable interior cavity accessible through an opening, said dispensing tube being fluid in communication with said opening into the expandable reaction chamber; and said chamber expands upon a reaction of at least said first reactant and said second reactant within said closed interior cavity of said chamber whereby the expansion of the chamber causes the gripper to outwardly expand, releasing the protruding portion of the vascular occlusion device.
