FIG 1. Schematic illustration of Neuroform-assisted embolization of a wide-necked superior hypophyseal aneurysm.

A, Microcatheter containing the stent was positioned over the wire distal to aneurysm location.

B, The stent was deployed by holding the stabilizing catheter in a fixed position while the 3F catheter was pulled back.

C and D, Interstices of fully expanded stent can easily accommodate microcatheter for coiling. Protrusion of coil loops in to internal carotid artery is prevented by the stent.
