The Wak device - which stands for Wearable Artificial Kidney - aims to replace dialysis machines, which require patients to visit a clinic several times a week.Currently, patients on dialysis have their blood filtered in three long sessions a week, which can be exhausting for patients.

HOW DOES IT WORK? 

The device is a 4.5kg (10lb) miniature dialysis machine that a patient can wear around their body.
It looks bulky at the moment, but researchers believe they can get the weight down to just 2.3kg (5lb), as well as reduce its size.

It connects to a large vein in the body through catheter which has filters to separate water, salts and minerals out of the blood.
The filters have to be replaced once a week, and chemicals added once a day to clean the water filtered out.

Seven patients in Seattle, who had end-stage kidney disease, wore the device for 24 hours.
The patients were also able to enjoy ice cream and cheesecake, which they weren't able to do on dialysis because it could lead to a dangerous build-up of minerals.

In a previous trials, participants were able to sleep with the devices, and were also be able to take showers and carry out other normal activities, Gura said.
But there was one major flaw. Two patients stopped wearing the device before the trial ended because of technical issues.

The team said they are now working to fix the problem.
'All patients reported that they would switch to the WAK if the device were commercially available,' the authors wrote.
If future trials prove successful, it has been given the green-light to be fast-tracked through the U.S. Food and Drug Administration's approval process.
