<p>A vascular occlusion device deployment system (10) is provided for deploying an embolic device (24) at a preselected site within the vasculature of a patient. The deployment system includes a tubular element (16) having a catch (22) movably located within the tubular element. The catch has a normal open configuration and a closed configuration. When in the closed configuration, the catch grasps a headpiece (29) of an embolic device. The tubular element has a constraining section (30) and a releasing section (32). When the catch is within the constraining section of the tubular element (16), the constraining section acts upon the catch to keep the catch in a closed configuration. When the catch is moved to the releasing section (52), the catch returns to its normally open configuration and releases its grasp of the embolic device (24) headpiece.
