1. INTRODUCTION TO NEUROFORM ATLAS
Caution: Investigational device. Limited by Federal
(United States) law to investigational use.

2. FDA -- Indications For Use
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.

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

4. Key Geometry Attributes
Distal
Proximal
Open cell distal end designed to aid in stent conformability and track
8 cell structural elements designed to provide support and anchoring
12 cell structural elements designed to provide flexibility, improve scaffolding, and prevent ‘gapping’ on a bend
Closed cell proximal end designed to aid in stent stability during lumen recross.
