  • NAISR: Stanford University North American Intracranial Stent Registry


  • Neuroform Stent for Wide-Neck Aneurysms

These stents are placed as an adjunct to coil embolization of wide-neck intracranial aneurysms. Use of the stent allows treatment of aneurysms that cannot be managed by coiling alone.


  • Onyx® HD-500 Liquid Embolic Agent for Wide-Neck Aneurysms

The Onyx HD-500 liquid embolic system is another tool for treating wide-neck intracranial aneurysms. Liquid Onyx is delivered into the aneurysm by a controlled injection through a micro catheter. Onyx is a polymer that solidifies within five minutes and occludes (fills in) the aneurysm.


Ischemic Stroke Research


  • Penumbra 3D Separator Investigational Device: A Randomized, Concurrent Controlled Trial to Assess the Safety and Effectiveness of the Separator 3D as a Component of the Penumbra System in the Revascularization of Large Vessel Occlusion in Acute Ischemic Stroke

  • RECOVER-Stroke Stem Cell Trial: A Phase2 Randomized, Controlled Study with a Phase I Safety Cohort testing ALD-401 Derived from Autologous Bone Marrow Delivered via Intracarotid Infusion in Subjects with Ischemic Stroke using Blinded Assessments



  • (Study Completed) PICS: Penumbra Imaging Collaborative Study

The PICS study is a multicenter trial to assess the outcome of acute ischemic stroke patients revascularized by the Penumbra™ System, a device used in mechanical thrombectomy therapy.


Intracranial Stenosis


  • Wingspan Stent for Intracranial Stenosis

The Wingspan stent system with angioplasty balloon catheter is a neuro-specific stent used to expand the lumen of cerebral arteries in patients with intracranial atherosclerotic disease that is refractory to medical therapy


Cerebral Vasospasm


  • NeuroFlo Perfusion Augmentation for Symptomatic Cerebral Vasospasm

The NeuroFlo Perfusion system augments cerebral perfusion, improving neurological outcome in patients with symptomatic vasospasm secondary to subarachnoid hemorrhage.


Quality & Outcomes Research


  • Neurointerventional Outcomes Database and Research

The purpose of this study is to monitor procedural data and patient outcomes of procedures performed in the department to improve overall quality of care.
