Hemotech’s venous needle won’t fall out!
Venous needle dislodgment can be fatal. And, since the pressure of blood returning to the body is negative, the machine may not alarm. Hemotech, a start-up in Sonoma County, CA, is working on a prototype of a new needle that will detect blood leaks—and stop the flow of blood.
First US human testing of the Wearable Artificial Kidney
The University of Washington is the first testing site for the Wearable Artificial Kidney (WAK) in up to 16 people. The battery powered device will continuously filter and reuse water, so it weighs just 10 lbs—but may get even lighter. See it for yourself.
Baxter’s Vivia home HD machine outside the US
Home HD trend lines outside the US are climbing! In England, about 4% of dialysis consumers use home HD (that’s about 4 times the US rate). Canada is at about 5%, and Sweden is close to 6%. In Australia,10% of people with ESRD use home HD. Baxter’s Vivia machine (approved in Europe but not yet in the US) is taking advantage of this trend.
What can Optiflow do for you?
Apparently, veins and arteries don't like being connected together to make an AV fistula. Optiflow is a mechanical connector that takes the place of sutures and helps keep the connection open.
Baxter’s New Vivia Home HD Machine is (Almost) Here!
Baxter presented human studies data at the ERA-EDTA Congress in Amsterdam this June supporting the safety and efficacy of the new Vivia home dialysis system. With four treatments per week for 10 weeks, averaging 3.8 hours per treatment, the mean weekly Kt/V of the 22 US patients was 2.97, with no serious adverse events related to the machine. A small nocturnal trial was also done in Canada.
A whole new 3D take on a dialyzer
A UCSD lab has already shown that it can use 3D printing with a soft hydrogel and living cells to form blood vessels. Now, researchers are using this technique to remove toxins from the body. Nanoparticles that can trap toxins are embedded in a hydrogel matrix. The gel turns red when toxins are present. Once the toxins are removed, the gel matrix can be turned off. This discovery may one day lead to entirely new ways to clean the blood after kidney or liver failure.
New portable artificial kidney trials to start in 2017
A wearable dialysis device prototype is targeted for next year, with clinical trials just 3 years off. A joint effort with Debiotech, AWAK, and Neokidney Development, the new device will be able to do longer and/or more frequent home HD. The system will be based on Debiotech’s DialEase. With AWAK’s sorbent equipment, just 4 liters of dialysate will be needed. Neokidney Development offers access to expert doctors, patients, and help to raise funding for the project.
For a new PD cycler, less will be more

New, mystery dialysis machine from Premier Biomedical
Whatever a "sequential dialysis machine" is (patent-pending, of course), Premier Biomedical has signed an agreement with Printed Device Concepts in El Paso to produce it. Hmmm.
Nanofiber mesh could be a cheaper option than dialysis
Researchers from Japan have developed a nanofiber mesh that contains absorbent minerals to soak up waste products from the blood. The new material can remove creatinine, and now will be tweaked to clean up other wastes as well. The goal is to have dialysis that is so small it can be worn on an arm.
Bioprinting with living "ink" may lead to transplantable human organs
3D printing has already created a human trachea built out of stem cells that has saved the life of a 2-year old. The new technology allows printing of tissue samples that can be kept alive on a microchip, using a blood substitute. Currently, printing is limited to one cell thickness deep, or the cells suffocate—but a Virginia foundation has offered a $1million dollar prize for the first 3D printed working liver, and perhaps kidneys will be next.
WAK Human Trials Approved
A wearable artificial kidney (WAK) is one step closer, with FDA approval of human clinical trials. The WAK is one of three kidney related products that has been fast-tracked by the FDA under a new program.
New Membrane Could Lead to Portable Dialyzers
"If patients are able to undergo dialysis more frequently and/or for longer periods of time, their fluid balance is better. The waste products in the blood do not accumulate between treatments and this means that patients feel better." So says Dr. Dimitrios Stamatialis, who is heading up a Dutch effort to develop new, biocompatible membranes, with the goal of lightweight, portable dialysis.
Wristwatch-sized Device Planned to Remove Uremic Toxins
A Japanese nanofiber polymer mesh is a new approach to toxin removal. Instead of diffusion, the mesh attracts and holds toxins with zeolites—adsorbent minerals. It's been tried on creatinine, but zeolites vary in their pore sizes to remove other toxins as well. The goal is a wristwatch-sized device that can be attached to a vascular access.
Europe gets a new home HD machine—maybe the US will be next!
Baxter has CE Mark approval for a new home HD machine that can deliver flex treatments—short daily, extended, and more frequent than the (unfortunately) standard 3 times a week. The system is user-friendly, with a touch screen, animated step-by-step instructions, a sensor that will stop the blood pump if a needle dislodges, wireless monitoring, and more. We hope the US will see this new technology next!
Australia technology to get patients home and help them stay there.
Telehealth, with remote monitors and video conferencing is being tested to boost home dialysis rates in Australia. The aim is to reach from the current level of 15% home dialysis patients in Victoria to the new Department of Health benchmark of 30-35%. The system collects weight and blood pressure data, which are looked at by a renal nurse. Video conferences help patients review needling and let nurses see exit sites to watch for infection.
A country with twice as many new dialysis patients/year as the US is aiming small

Their new DiCAT (Dialysis Platform for Communication, Assistance, and Training) product will help support people on home dialysis.
Learn what a self-assembling, nano material might do for you one day
Bioartificial kidneys made out of a new, self-healing polymer would have less chance of rejection, say scientists. The new material is being tested to design and mimic human cells—and they build themselves. If this process works, it could be a way to offer portable dialysis, aid transplant, or help form a new type of sutures for surgery.
New partners plan to build a miniature home HD machine!
AWAK's loss may be your gain. The Singapore-based company ran out of funding for a wearable artificial kidney—but has reinvented itself in a new partnership with Swiss Debiotech to create an "extremely small and convenient to use" home HD machine based on sorbent technology.
