TRANSCRANIAL ULTRASOUND THROMBOLYSIS SYSTEM AND METHOD OF TREATING A STROKE

摘要

A method of transcranial ultrasound thrombolysis comprises the steps of providing a predetermined level of ultrasonic energy substantially throughou t a primary treatment zone encompassing the M1 branch and M2 branches of the middle cerebral artery of an individual. A thrombolytic agent is also administered to the individual. A transcranial ultrasound thrombolysis syste m (10) is also provided that includes a transducer (20). The transducer is adapted to provide a predetermined level of ultrasonic energy substantially throughout a primary treatment zone encompassing at least a substantial portion of the M1 branch and the M2 branches of the middle cerebral artery i n one hemisphere of a brain.
