“The high prevalence of AKI in cardiac surgery today is a well-known risk. We look forward to building further clinical validation that RenalGuard Therapy can provide the solution to reduce the prevalence of CSA-AKI, the length and cost of hospitalisation, and most importantly to improve patients’ quality of life.”

Compared to the standard of care, RenalGuard was found to significantly reduce the incidence of Contrast-Associated AKI in two investigator-sponsored studies.

The system comprises a console and RenalGuard Single-Use Set for infusion and urine collection.

The single-use set includes a urine collection set and infusion set, which connect to a patient’s Foley catheter and standard IV catheter, respectively.

The console measures the urine volume in the collection set and delivers an equal volume of hydration fluid through the infusion set.

It works based on patented software and electronic weight measurements for monitoring the urine volume and controlling the fluid infusion rate.
