Polymers to trap uremic toxins in WAK (Wearable artificial kidney)



Chemistry and Materials | Medical Devices

The Technology

Renal failure is a medical condition in which the kidneys fail to function adequately. The treatment given to patients suffering from renal failure are dialysis or kidney transplant. Different studies done in recent years, indicate that frequent and prolonged dialysis treatment is associated with remarkably improved outcomes in these patients. Therefore, there is a growing demand for true practical wearable artificial kidney (WAK) or a portable dialysis system, which will allow prolonged treatment. The blood purification in WAK systems is based on extracorporeal cleaning by trapping different uremic toxins.

The technology offers sorbent modified polymers compounds that allows better removal of the uremic waste compounds. In addition it possess excellent strength, good mechanical properties and resistance to extremes of pH, oxidation and acid catalyzed hydrolysis.


  • Improved life quality of the patient by cancelling the need for hospital treatment
  • Can be used for both Peritoneal and Hemodialysis
  • Effective removal of the uremic waste compounds

Applications and Opportunities

  • Artificial kidney
  • Peritoneal dialysis and Hemodialysis
