Procedure of FD deployment using the push-pull technique, illustrated in an idealized sidewall aneurysm. (A) Advancing FD through microcatheter to the targeting site (from right to left); (B) FD is completely placed into microcatheter and across aneurysm orifice; (C) Pulling back the microcatheter to partially release the FD; (D) Pushing forward the microcatheter while holding the delivery wire (attached to the distal coil) to “pillow” the FD to gain apposition to the vessel wall; (E) Releasing the distal constraint to expand the FD; (F) Pulling back the microcatheter and pushing forward the delivery wire/pusher to completely release the FD.
