Catheter-associated urinary tract infections (CAUTIs) affect over one million patients in the United States annually and contribute to approximately 13,000 deaths and $1B in healthcare costs. Two-thirds of CAUTIs develop due to Foley catheter design flaws that limit urine flow and allow bacterial colonization on the catheter’s external surface.

AdvanceCath is a flexible, indwelling catheter that keeps the sphincter and prostate urethra open, which allows urine to flow around the entire catheter and eliminates the space where bacteria typically spreads. A condom-like catheter collects urine and stores it in a sterile bag. The system also has the ability to flush the urethra with an antibacterial solution to reduce risk of infection further. A bladder retention mechanism under development includes a fail-safe component that will collapse the retention component under excessive pressure and prevent damage to the urethra as the device is removed.
