Inclusion Criteria: * Age ≥ 18 and ≤ 80 years old, * Patient has at least one unruptured intracranial aneurysm intended to be treated with Silk Vista * Has an untreated or recanalized, unruptured or previously ruptured aneurysm whose rupture occurred \>30 days prior to the index procedure * Able and willing to comply with study procedures including returning to the study site for imaging exams * Able and willing to give oral informed consent Exclusion Criteria: * Any criteria for non- or contraindication to endovascular treatment and/or flow-diverting stent placement (e.g., suspected mycotic aneurysm, including those caused by a left atrial myxoma, systemic bacterial infection, contraindication to antiplatelet drugs (aspirin, clopidogrel/Plavix, ticagrelor, and heparin), local or general anesthesia, allergy to the contrast agent required for treatment by the diversion technique, known severe allergy or hypersensitivity to nickel, titanium, tungsten, or platinum; cost of treatment for an intracranial aneurysm within the last 6 months; and for women, pregnant, or currently breastfeeding) * Has a true bifurcation aneurysm, defined as an aneurysm (saccular or non-saccular) located at a point of vessel bifurcation * Has vessel characteristics, such as severe tortuosity, stenosis, or morphology that would preclude safe endovascular access to the target aneurysm necessary for treatment with the study device. * Presence of intracranial atherosclerotic disease. * Received previous …
