NanoVibronix, Inc. announced it has filed a new provisional patent application with the United States Patent and Trademark Office (“USPTO”) entitled “Multiple Frequency Surface Acoustic Waves for Internal Medical Device” (the “Patent Application”) related to its UroShield. The Patent Application covers a recently developed enhancement to the UroShield product, UroShield “Ultra”, which incorporates improvements to the Company's original UroShield. The next generation UroShield Ultra includes modified housing that is designed to improve catheter coupling and incorporates multiple actuators that work in sequence to discourage bacterial docking by delivering SAWs at multiple frequencies directly to indwelling catheters.
