A non-invasive imaging vibrator for use in remediation of blood flow disturbances comprising a vibration source operable to generate vibration at a frequency in the range of 1- 1000 Hz and a phased array imaging transducer operatively attached to an active end of the vibration source, thereby enabling targeting of vibration via an image generated on an ultrasonic display. The preferred imaging vibrator is operab le to emit vibration in the low frequency sonic range with an amplitude of about 0.1 mm - 15 mm (and more preferably at least 2 mm), such as to provide an effective transthoracic tool for acute coronary applications. In a variation, means for emitting a therapeuti c low frequency ultrasonic waveform in concert with vibration in the range of 1- 1000 Hz (wherein both waveforms are simultaneously directed by high frequency ultrasonic imaging) is also provided.
