About the Solution
We have created a portable artificial kidney device that fits into a backpack that can be used at night or at work while sitting on a nearby table. Moreover, taking advantage of the fact that the device does not need water or dialysate, we will use the same technology to create for the first time a completely implantable artificial kidney. Patients are very enthusiastic about our portable and implantable artificial kidney devices because they offer more personalized treatment than dialysis and because of the more accurate ability to control fluctuations in toxins to be removed. Importantly, patients are also excited about the improvement in their quality of life because of the ability to use the device at home or at work coupled with the increased ease of treatment. In addition, for patients who chose to remain on peritoneal dialysis, our technology offers the advantage of decreasing the number of treatment fluid exchanges needed. The important advantages of our technology to patients include:
- Since the use of the device occurs at night or during the day at home or at work, patients will no longer need to go to a dialysis clinic and will have increased mobility to travel and work
- The technology will provide patients with more treatment options
- Dialysate solutions, large R/O water tanks and large storage space for home modalities will no longer be needed decreasing the overall cost of treatment
- Given the potential for greater clearances and efficiency of treatment, the diet and fluid intake can be liberalized
- In its ultimately implantable format, patients will be entirely mobile and not require a CVC line or access
- Given the shortage of kidneys for transplant, patients who have dreamt for years of getting off dialysis will now be offered this opportunity
