Publication number: 20150011929Abstract: A device and method of the present invention provides application of low-energy acoustic waves to indwelling surfaces of a catheter in order to remove and prevent microbial biofilm formation. The low-energy acoustic waves are generated by an electrically activated piezo element. The device can take the form of a luer connector configured to couple to the hub of the indwelling catheter or can take the form of a catheter insert. The characteristics of the acoustic waves can be varied in order to inhibit bacterial adhesion to the indwelling surfaces of the catheter. Moreover, the characteristics of the acoustic waves must also be in a range so as to not induce bacterial adhesion to the indwelling catheter surfaces.Type: ApplicationFiled: February 18, 2013Publication date: January 8, 2015Inventors: Shuja Dawood, Adam Clark, Nathaniel Moller, Luis Soenksen, Soumyadipta Acharya, Steven Hsu, Clifford Weiss
