The Solitaire™ Platinum Revascularization Device is indicated for use to restore blood flow in the neurovasculature by removing thrombus for the treatment of acute ischemic stroke to reduce disability in patients with a persistent, proximal anterior circulation, large vessel occlusion, and smaller core infarcts who have first received intravenous tissue plasminogen activator (IV t-PA ). Endovascular therapy with the device should be started within 6 hours of symptom onset. The Solitaire™ Platinum Revascularization Device is indicated to restore blood flow by removing thrombus from a large intracranial vessel in patients experiencing ischemic stroke within 8 hours of symptom onset. Patients who are ineligible for IV t-PA or who fail IV t-PA therapy are candidates for treatment.. The Solitaire™ Platinum revascularization device, featuring Parametric™ design, a unique overlapping stent retriever-based technology, restores blood flow and retrieves clots from occluded blood vessels in the brain for patients experiencing acute ischemic stroke (AIS) due to a large vessel occlusion (LVO)..
