Integrated System for Bacterial Detection and Biofilm Treatment On Indwelling Urinary Catheters 170 177 IEEE Transactions on Biomedical Engineering (TBME)
This work aims to integrate a bacterial biofilm sensing and treatment system with a commercially available Foley urinary catheter for managing catheter-associated urinary tract infection (CAUTI). The system comprises a flexible impedance sensor seamlessly integrated with the inner catheter surface via a 3D-printed insert. The electrodes also apply a bioelectric effect-based treatment that provides a synergistic reduction in the biofilm on the surface. The entire system is controlled by a custom PCB communicating wirelessly with a mobile application to facilitate implementation by researchers and clinicians. This system represents a significant step forward for managing CAUTI using device-based approaches. read more
