Claim Text:
1. A vaso-occlusive coil delivery assembly, comprising: a pusher assembly defining a longitudinal axis; an elongate tubular member having a proximal end portion attached to a distal end of the pusher assembly, the tubular member being aligned with the longitudinal axis of the pusher assembly and having a tubular member wall; a vaso-occlusive coil defining an axial lumen and having first and second vaso-occlusive coil windings in a proximal end portion thereof, the first and second windings defining a vaso-occlusive coil opening therebetween, wherein a distal end portion of the tubular member wall extends into the axial lumen of the vaso-occlusive coil; and a locking pin extending through the vaso-occlusive coil opening and through the distal end portion of the tubular member wall disposed in the axial lumen of the vaso-occlusive coil, thereby locking the tubular member to the vaso-occlusive coil, wherein a central portion of the tubular member proximal of the locking pin is configured to be selectively severed from the proximal portion, so as to detach the vaso-occlusive coil from the pusher assembly.
