Abstract
An insertion device of a coil includes a delivery wire driving unit, a secondary catheter driving unit, and a control circuit. A platinum coil for coil embolization is attached to the tip of a delivery wire. The delivery wire driving unit is provided in the proximity of the entrance of a Y connector such that the delivery wire is advanced and moved back. The secondary catheter driving unit is provided in the proximity of the entrance of a Y connector such that the secondary catheter is advanced and moved back. The control circuit controls the delivery wire driving unit so as to insert the delivery wire by a predetermined insertion force. If the delivery wire cannot be inserted, the control circuit controls the secondary catheter driving unit such that the secondary catheter is advanced after being moved back, and then controls the delivery wire driving unit so as to insert the delivery wire.
