by The Promise of Portable Dialysis
Kidney failure requiring dialysis imposes major lifestyle limitations on patients, restricting their ability to travel or live normal daily lives. A wearable artificial kidney could potentially liberate those dependent on dialysis by allowing consistent blood filtrations regardless of location. Researchers are making exciting progress towards developing such a device which could be worn similar to a piece of clothing or attached to the body like an insulin pump.
Miniaturizing the Kidney’s Functions
One of the greatest design challenges is miniaturizing the complex functions of a natural kidney, which filters over 100 gallons of blood per day, into a small portable device. Global Wearable Artificial Kidney remove waste and excess fluid from the blood through intricate filtering units called nephrons. Engineers are working to design micrometer-scale filtration membranes and dialysate channels that can perform these tasks external to the body at a sufficient rate. Early dialysis devices were the size of a refrigerator but advances in microfluidics, polymer membranes and sensor technologies could enable a miniaturized wearable version.
Promising Global Wearable Artificial Kidney Prototypes
Several research groups have developed early-stage wearable prototypes and tested them in animals. A team at the University of California, San Francisco developed a watch-sized device that was able to effectively filter blood when connected to sheep kidneys for up to 8 hours. The German company Fresenius Medical Care tested a portable membrane-based device on pigs, demonstrating it could filter blood at clinically meaningful levels for up to 12 hours continuously. These proof-of-concept studies highlight the feasibility of a fully wearable approach.
Overcoming Engineering and Safety Hurdles
However, significant obstacles still remain before a wearable kidney can become a viable clinical therapy for humans. Ensuring biocompatibility and preventing infections from frequent blood access points will be crucial safety hurdles. Engineering challenges include optimizing device size, power supply, waste disposal methods and controlling fluid flows at the low volumes necessary. Regulatory approval will also require demonstrating long-term safety and effectiveness through extensive human trials. Despite the difficulties, researchers are making steady progress addressing each component challenge through ingenuity and multidisciplinary collaboration.
Partnerships to Accelerate Development
To help accelerate development, Global Wearable Artificial Kidney foundations and private benefactors are forming partnerships with engineers and clinicians. The NIH and DARPA have provided targeted funding to wearable kidney projects through initiatives like the Medical Device Innovation Consortium. In 2019, the charitable foundation KidneyX awarded $2.7 million to seven researchers and startups to advance wearable technologies. Prizes like the XPRIZE Global Learning Machine provide additional incentives for open collaboration towards establishing clinical prototypes within 5-10 years. With continued support, experts believe a functional portable dialysis device capable of improving patients’ quality of life could potentially be available within the next decade.
Regulatory Pathways and Early
Regulators will play a key role in determining approval pathways for novel wearable medical technologies. For early applications, devices may gain clearance first for short-term acute situations such as during surgery versus chronic use in end-stage kidney disease patients. Portable dialysis could have immediate benefits for situations like disasters or remote/rural locations lacking fixed infrastructure. The military has expressed interest in a wearable system to maintain soldier health in field conditions. As components are proven, markets may expand to support patients travelling or resuming more active lifestyles no longer restricted to clinic schedules. With coordinated efforts, a wearable artificial kidney promises to transform care for the over 750,000 people in the US and millions worldwide dependent on in-center hemodialysis
The Future is Global Wearable Artificial Kidney
Steady progress is being made towards developing the first functional wearable artificial kidney. Miniaturizing vital organ functions into portable forms remains a major technical challenge but one that holds enormous promise to improve quality of life for those suffering from kidney disease worldwide. Through open collaboration and continued patient advocacy, researchers are working tirelessly to overcome remaining obstacles and accelerate clinical translation. If successful, a wearable version could liberate dialysis patients and herald a new era of portable medical technologies keeping individuals healthy anywhere life takes them. With the right resources and partnerships, the future of replacing vital organ function may indeed be wearable.
