Improves Patient Outcomes
The patented Light Line PhotoDisinfection System uses 405 nanometer visible light (light that the human eye can see) to safely and effectively kill the pathogens that cause catheter infections without harming surrounding tissue or catheter components.
The System, shown below, includes a reusable laser light engine, transfer cable and disinfecting fiber:
Developed through years of research and testing, Light Line’s proprietary etching technology creates patterns of microscopic holes in the outer coating of an optical fiber. This allows the light at the optimal therapeutic dose to cause cellular disruption and kill pathogens without the use of drugs, chemicals, or harmful UV light. Light Line targets the most critical area, which accounts for 91.5% of the peritonitis cases. By directing the light to specific areas of catheters and other medical devices Light Line’s visible light disinfecting technology kills microbes exactly where they reside.
Studies conducted by Light Line have shown that this disinfecting light treatment has killed high concentrations of the microbes that lead to catheter infections, including bacteria, yeast and fungi.
The technology is protected by over 30 U.S. and international patents. These patents provide broad coverage for the use of this technology in catheters and other medical devices. In addition, these patents provide coverage for many other applications. These patents cover the novel aspects of our disinfecting light technology. There is no other system like it.
Light Line Medical’s Revolutionary PhotoDisinfection System is compatible with standard catheters and other medical devices such as endotracheal tubes. The system is designed to dramatically decrease the frequency of peritoneal dialysis infections, urinary tract infections, bloodstream infections, and ventilator-associated pneumonia. Here’s how it works.
Below are images of catheters inoculated with ampicillin-resistant bacteria before and after light treatment. In each case, the image on the right shows bacteria on the extraluminal catheter surfaces with light treatment as compared to the control (no light) group on the left.

Data presented at the 43rd Annual Dialysis Conference in March 2023 demonstrated that the Light Line PhotoDisinfection System killed peritoneal dialysis-related microbes:
