Patent attributes
A vascular occlusion device deployment system for deploying an occlusion device at a preselected site within the vasculature of a patient. The deployment system includes a pusher which has a constrictor located at the distal end portion of the pusher. The constrictor has a channel which receives a portion of the occlusion device. The constrictor has a proximal end portion and a distal end portion wherein the proximal end portion can be moved relative to the distal end portion to reduce the size of the channel. When the channel size is reduced, the constrictor grasps the portion of the occlusion device located within the channel. When it is desired to deploy the coil, the constrictor is moved in the opposite direction to increase the size of the channel and release the coil's grasp of the occlusion device.
