A method for delivering ultrasound energy to a patient's intracranial space involves forming at least one hole in the patient's skull, advancing at least one ultrasound delivery device at least partway through the hole(s), and transmitting ultrasound energy from the ultrasound delivery device(s). According to various embodiments, ultrasound delivery devices may be advanced into the epidural space, one or both ventricles and/or an intracerebral space of the patient's brain. In alternative embodiments, one or multiple holes may be formed in the skull, and any number of ultrasound delivery devices may be used. Intracranial ultrasound delivery may be used in treatment of ischemic stroke, head trauma, atherosclerosis, perfusion disorders and other acute or chronic neurological conditions. |
