Patent attributes
A vascular occlusion device deployment system is provided for deploying an embolic device at a preselected site within the vasculature of a patient. The deployment system includes a tubular element having a catch 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 of an embolic device. The tubular element has a constraining section and a releasing section. When the catch is within the constraining section of the tubular element, the constraining section acts upon the catch to keep the catch in a closed configuration. When the catch is moved to the releasing section, the catch returns to its normally open configuration and releases its grasp of the embolic device headpiece.
