DETACHABLE PUSHER-VASOOCLUSIVE COIL ASSEMBLY

摘要

A coil 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 slidably received within the lumen (18) of a catheter (12) or an introducer (34), the wire (22) havin g at its distal end a stiff wavy wire (28) segment adapted to frictionally and releasably engage a vaso- occlusion 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 vas o- occlusion coil with the device.
