HW567

The Neuroform Atlas (Atlas) Stent System is intended to be used for stent assisted embolization for intracranial aneurysm therapy. The purpose of the stent is to retain the occlusive devices within the aneurysm. Occlusive devices can be delivered prior to stent placement or after stent placement. The Atlas Stent System consists of a self-expanding, sterile, nitinol stent preloaded over a delivery wire inside an introducer sheath. The sheath and delivery wire are used to transfer the stent into a 0.0165 to 0.017 inch internal diameter microcatheter. After transferring the stent, the sheath is removed from the proximal end of the delivery wire. The delivery wire is then used to advance the stent to the distal end of the microcatheter. The microcatheter and stent system are repositioned as a unit to ensure the stent is located across the aneurysm. The stent is deployed by stabilizing the delivery wire and withdrawing the microcatheter. The Neuroform Atlas stent cannot be repositioned or captured once deployed.
