The Neuroform Atlas Stent System is indicated for use with
bare metal embolic coils for the treatment of wide-neck
intracranial, saccular aneurysms arising from a parent
vessel with a diameter of greater than or equal to 2mm and
less than or equal to 4.5mm. Wide-neck aneurysms are
defined as having a neck greater or equal to 4mm or a
dome-to-neck ratio of less than 2.

1. Designed for all sizes of the stent to be delivered
through 0.0165in (e.g. SL-10) or 0.017in (e.g. XT-
17) microcatheter
2. Design is optimized for conformability
3. Designed for superior deployment ease & accuracy
4. Designed for feature improved coil scaffolding
