Patent ID: 8202292

Claim:
An occlusive coil delivery device, comprising: an occlusive coil comprising a plurality of windings, the occlusive coil having a proximal end and a distal end, the proximal end of the occlusive coil comprising a plurality of open pitched windings; a delivery wire assembly comprising a proximal tubular portion and a distal coil portion and lumen extending at least partially there through, the delivery wire assembly comprising a delivery wire forming a first conductive path extending at least partially within the lumen from a proximal end of the delivery wire assembly to a location distal of the distal coil portion, said delivery wire extending distal of the distal coil portion and comprising an electrolytic detachment zone, the delivery wire assembly further comprising a second conductive path formed by the proximal tubular portion and distal coil portion; and a delivery wire adapter having a proximal end and a distal end, the distal end of the adapter comprising a plurality of fingers configured to interface between adjacent open pitched windings of the proximal end of the occlusive coil, the proximal end secured to a distal portion of the delivery wire.
