Bringing Light to
Catheter Disinfection

LIGHT LINE MEDICAL™, INC., has developed a proprietary, patented PhotoDisinfection System that uses visible light (not harmful UV light) to prevent and treat catheter-associated infections, including those caused by antibiotic resistant-pathogens.

Catheters are necessary life saving devices — infections limit their use. With Light Line’s technology designed to prevent and treat catheter infections, patients can receive the best catheter care available.


The light delivery has been refined with precision, allowing disinfection of both the inside and outside of translucent off-the-shelf catheters. This platform technology is engineered to prevent and treat infections in peritoneal dialysis, central, and urinary catheters, as well as PICC lines and endotracheal tubes.

The Problem:

Catheters are critical. They are the best and most efficient way to access vessels, organs, and other tissue to treat peritoneal, urinary, respiratory, and vascular diseases. However, catheter-related infections limit their use and can lead to a failure of catheter therapy, requiring aggressive antibiotic treatments to resolve.


Sterilization techniques, antimicrobial coatings, and drugs are simply not effective. These conventional treatments have exacerbated the spread of drug-resistant microbes (e.g., MRSA, ERSA) that overwhelm hospitals, care centers, and homes. These prolific, drug-resistant microbes are responsible for:

  • A significant number of injuries and deaths
  • Reducing the medical benefits associated with catheter treatments
  • Increasing the cost of medical care. Annually hospital-acquired infections (HAIs) alone cost $50 billon and cause over 100,000 deaths.

The Solution:

The Light Line PhotoDisinfection™ System disinfects all catheters, endotracheal tubes, and other medical devices. Our data is conclusive – this light-based technology, also known as photonics, kills microbes, even drug resistant varieties, when used with various catheters. This allows for extended catheter use resulting in improved medical outcomes, thus saving lives and reducing costs.

The Technology is Designed to:

PREVENT INFECTIONS and reduce complications arising from them.
KILL MICROBES, including drug resistant pathogens.
SAVE HEALTHCARE COSTS, including statutory penalties in the U.S.
EASE (Enable safer and more effective) catheter therapy in hospitals, clinics, or in the patient’s home with minimal training requirements.

Light Line™ PhotoDisinfection Peritoneal Dialysis Catheter
Current dialysis patients fear infection. Peritoneal dialysis infections are a major reason that patients choose hemodialysis over peritoneal dialysis. Experts agree that peritoneal dialysis is typically better for the patient and their quality of life - - it costs less than hemodialysis and has a higher 5-year survival rate. Experts also agree that many more patients need to be switched from hemodialysis to peritoneal dialysis.

Foley/Urinary Catheter
Catheter-Associated Urinary Tract Infections (CAUTIs) are one of the most common infections a person can contract in the hospital or nursing home. Indwelling catheters cause these infection. These CAUTI’s are deadly, place an unnecessary burden on the healthcare system, and must be eliminated.

Light Line™ PhotoDisinfection Endotracheal Tube
Ventilator-Associated Pneumonias are nosocomial pneumonias that typically develop more than 48-72 hours after endotracheal tube intubation. It is the most common infection acquired by adults and children in ICUs and is a cause of significant patient morbidity, mortality, and unnecessary expense.

Light Line™ PhotoDisinfection Central and PICC Lines
Central Line Associated Bloodstream Infections (CLABSIs) are some of the most serious infections, typically causing a prolonged hospital stay, increased cost, and risk of mortality. In 2021, in the U.S. approximately 28,000 patients died in ICUs from a CLABSI. Unfortunately, these infections are becoming more deadly.
