АКУСТИЧЕСКОЕ УПРАВЛЕНИЕ ЭМБОЛИЯМИ В ОРГАНИЗМЕ

摘要

A device ( 30 ) for controlling a flow of emboli ( 48 ) in an aorta ( 36 ) of a patient. The device includes an ultrasonic transducer ( 44 ), which is configured to transmit an ultrasonic beam ( 52 ) into the aorta in a vicinity of a great origin of a neck vessel ( 38 ). A driver circuit ( 58 ) is coupled to drive the ultrasonic transducer to generate the ultrasonic beam at a frequency and power level sufficient to divert at least a target fraction of the emboli of a given type and size away from the neck vessel.
