ABSTRACT:
Ultrasonic, sonic or vibratory energy, delivered non-invasively, minimally invasively or invasively (e.g. surgically), is utilized to provide direct cleaning action at or to the location of the implanted device such as a prosthetic heart valve with undesirable deposits of at least some amount thereon or therein. Such ultra-sound energy may be aided by the use of a drug in association or cooperation with the acoustic irradiation. The “cleaning” acoustic energy may optionally be delivered under the guidance of an imaging modality and may be delivered in a timed or gated manner such that the valve occluders or leaflets are in a preferred position (assuming they are functioning) during exposures.
