Redesign Dialysis, Phase 2

Total prize amount:$3 Million

Building off the success of KidneyX’s inaugural prize competition (Redesign Dialysis Phase 1), Redesign Dialysis Phase 2 challenged participants to build and test prototype solutions, or components of solutions, that can replicate normal kidney functions or improve dialysis access.


  • Sought prototype solutions, or components of solutions, that could replicate normal kidney functions
  • Testable devices that could perform one or more of the following functional areas: blood filtration, electrolyte homeostasis, volume regulation, toxin removal and secretion, filtrate drainage and connectivity, dialysis access

Projected Impact

New solutions that could improve quality of life for patients
