Patent abstract
A urinary catheter clip-on device applies surface acoustic waves of Rayleigh-Lamb and/or Love type to a urinary catheter for preventing biofilms on the catheter surfaces. The bacteria is forced to move relative to the vibrating catheter surface. The amplitudes of bacteria vibrations are in nanometer range. The relative motion of bacteria results in bacteria quorum sensing, and disrupts the bacteria attachment process. The method is preventive as surface acoustic waves create low acoustic energy and bacteria is not killed.
