Endovascular therapy with the device should be started within 6 hours of symptom onset. 2. The pRESET LITE Thrombectomy 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 thrombolytic therapy or who fail thrombolytic therapy are candidates for treatment.
