The Neuroform Atlas Stent System is a Humanitarian Device that is authorized by Federal Law for use with neurovascular embolic coils in patients who are 18 years of age or older, for the treatment of wide neck, intracranial, saccular brain aneurysms which are not amenable to treatment with surgical clipping. There is no specified maximum number of patients who will be treated at this facility. There are no specific restrictions based on gender, child-bearing potential, breast feeding or contraception requirements for this device. Patients with angiographically documented wide-neck, intracranial, saccular aneurysms, either ruptured or unruptured, who are deemed by the attending neurointerventionalist to be acceptable candidates for endovascular embolization. The average percentage of patients who present with a wide necked aneurysm is collectively 15% of all identified cerebral aneurysms. There are no gender restrictions. The Neuroform ATLAS Stent System has not been studied in women who are pregnant or lactating.
