摘要：
Methods and systems are provided for treatment of medical devices using surface acoustic waves (SAW) of Rayleigh, “pseudo” Rayleigh and Lamb type. In some embodiments, use of such SAW is controlled such that relative velocity of bacteria is achieved wherein the vibration amplitude of the bacteria is smaller than a Z-potential repulsive zone of the bacteria, thus preventing biofilm formation on the medical devices. In some embodiments, systems of the present invention are powered by body movements, and may also provide a feedback loop for control of parameters. In some embodiments, the medical devices of the present invention are comprised of piezoelectric material, and act as self-actuators for the system.
