Ambulatory Hemodialysis-Technology Landscape and Potential for Patient-Centered Treatment

Area of Science:

• Nephrology
• Biomedical Engineering
• Medical Devices

Background:

• Chronic kidney disease (CKD) is a growing global health concern, with end-stage kidney disease (ESKD) often requiring kidney replacement therapy.
• Current in-center hemodialysis in the US has limitations, including patient burden and fewer long-term benefits compared to kidney transplantation.
• Intensive hemodialysis shows clinical promise but faces barriers to adoption due to equipment complexity and patient concerns.

Purpose of the Study:

• To explore the motivation behind developing ambulatory hemodialysis.
• To review essential technologies for future wearable and implantable hemodialysis devices.
• To present the evolution from early hemodialysis work to current wearable and implantable device development.

Main Methods:

• Review of historical hemodialysis pioneering work.
• Analysis of recent clinical experience with a wearable hemodialysis unit.
• Examination of ongoing development of implantable devices for kidney replacement.

Main Results:

• Ambulatory hemodialysis devices present a viable alternative for self-care and frequent, prolonged treatments.
• Wearable hemodialysis units have been successfully used in patient trials.
• Implantable hemodialysis devices are under development, aiming for a new paradigm in kidney replacement therapy.

Conclusions:

• Ambulatory and implantable hemodialysis technologies hold significant potential to improve quality of life and treatment outcomes for CKD patients.
• These advanced devices aim to overcome the limitations of conventional hemodialysis and offer greater patient autonomy.
• Continued innovation in wearable and implantable devices is crucial for advancing kidney replacement therapy.
