Abstract
Systems and methods for infection prevention and treatment in biological conduits using electroporation or pulsed field ablation (PFA). The system includes an elongate member, such as a dialysis catheter, vascular access device, or peritoneal dialysis conduit, with at least one electrode positioned along, within, or around the member. A control unit applies pulsed electric fields to inhibit microbial colonization, disrupt bacterial biofilms, and alter permeability of bacterial or endothelial cells to enhance sterility' or fluid, exchange. The system may use real-time impedance monitoring, microbial detection, or fluid composition analysis to adjust electroporation parameters. Electroporation may synchronize with dialysis cycles or antimicrobial lock solutions. The method includes automated, clinician-controlled, or sensor-triggered treatments to reduce infections and improve device longevity. The system provides an alternative or augment to antibiotics, reducing the risk of drug-resistant infections while improving the longevity and safety of medical implants.
