Stryker announced the Premarket Approval (PMA) of the Neuroform Atlas Stent System by the U.S. Food and Drug Administration (FDA). Neuroform Atlas is only the second aneurysm adjunctive stent to be granted PMA approval for the treatment of wide-neck, intracranial aneurysms in conjunction with embolic detachable coils. Neuroform Atlas Stent System was previously approved under a humanitarian device exemption restricting use to specific hospitals with institutional review board approval. PMA approval was granted based on robust clinical trial evidence proving the efficacy of the device.
"Neuroform Atlas represents a significant advancement in the treatment of wide-neck aneurysms which is now backed by the largest IDE stent-coil trial completed to date," said Dr. Osama O. Zaidat, Director of the Neuroscience and Stroke Center at Mercy Hospital in Toledo, Ohio, and Co-Principal Investigator of the U.S. Neuroform Atlas investigational trial. "More impressive were the results with an 84.7% primary efficacy rate, a 4.4% primary safety rate and a 3.8% retreatment rate."
"Enhanced stent conformability, a low-profile delivery system and high deployment accuracy even in distal anatomy puts Neuroform Atlas in a category of its own," said Dr. Brian Jankowitz, Director of the NeuroEndovascular Fellowship program at the University of Pittsburgh Medical Center and Co-Principal Investigator of the study. "This product is changing my clinical practice by allowing more patients with difficult aneurysms an option at endovascular treatment while improving the quality and safety of treatment."

Stryker's Neuroform Atlas Stent System is a self-expanding nitinol stent used in conjunction with metal coils to pack weakened blood vessel sacs called aneurysms within the brain. The stent is positioned across the aneurysm neck to hold metal coils and occlude the aneurysm. An estimated 6 million people in the United States have an unruptured brain aneurysm of which roughly 25,000 are treated each year.
The Neuroform Atlas Stent System is indicated for use with neurovascular embolization coils in the anterior circulation of the neurovasculature for the endovascular treatment of patients ≥ 18 years of age with saccular wide-necked (neck width ≥ 4 mm or a dome-to-neck ratio of < 2) intracranial aneurysms arising from a parent vessel with a diameter of ≥ 2.0 mm and ≤ 4.5 mm.
