Wearable Artificial Kidney to Be Tested For Safety and Effectiveness in Collaboration with FDA

A wearable artificial kidney, designed as a new treatment for kidney failure, will be tested in Seattle. The trial will be done in collaboration with the Food and Drug Administration under a new Innovations Pathway announced Monday.

The battery-powered wearable artificial kidney in its current form weighs about 10 pounds and is worn in a belt around the waist. Dr. Victor Gura, an associate clinical professor at the David Geffen School of Medicine, University of California, Los Angeles, invented the device. His goal is to free end-stage kidney disease patients from being tethered for several hours for three or more days a week to a dialysis machine. The hope is to improve the quality of life of these patients. (more…)
