INTRODUCTION TO NEUROFORM ATLAS

Caution: Investigational device. Limited by Federal(United States) law to investigational 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.

FDA -- Indications For Use


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

Top Performance Criteria


Key Geometry Attributes

Distal Proximal

Closed cell proximal end designed to aid in stent stability during lumen recross.

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

Open cell distal end designed to aid in stent conformability and track

• Atlas cells are designed to have an improved coil scaffold while retaining microcatheter recrossability.

Unique Cell Architecture

“Nano”Sized

Re-crossable



• Lowest track force required to advance stent

Ease of Access

>50% lower track force
