DETACHABLE PUSHER-VASOOCLUSIVE COIL ASSEMBLY

摘要

A coil-delivery device (20) for delivery of a vaso-occlusion coil (11) to a vascular target site via a catheter (12) is disclosed. The device includes a wire (22) adapted to be slidable received within the lumen (18) of a catheter (12) or an introducer (34), the wire (22) having at its distal end a stiff wavy wire (28) segment adapted to frictionnaly and releasably engage a vasoocclusion coil (11) by the end-region inner lumen of the vaso-occlusion coil. Also disclosed are a catheter assembly employing the coil-delivery device, and a method of releasably engaging a vaso-occlusion coil with the device.
