Innovations in Wearable and Implantable Artificial Kidneys

Area of Science:

• Biomedical Engineering
• Nephrology
• Medical Devices

Background:

• Over 2 million individuals globally require treatment for end-stage renal disease (ESRD).
• Current renal replacement therapies (RRTs) include hemodialysis, peritoneal dialysis, and transplantation, with ongoing efforts to enhance patient survival and quality of life.
• Advancements in sorbent technology, nanotechnology, and cell culture are driving innovation in ESRD management.

Purpose of the Study:

• To review emerging technologies for end-stage renal disease (ESRD) management.
• To describe the potential advantages and limitations of wearable artificial kidneys (WAKs) and implantable artificial kidneys (IAKs).
• To assess the impact of these novel devices on self-care RRT accessibility and healthcare economics.

Main Methods:

• Review of current and investigational renal replacement therapies.
• Description of wearable artificial kidneys (AWAK, WAK) and implantable artificial kidneys (IAK).
• Analysis of technological advancements and their application in artificial kidney development.

Main Results:

• Wearable artificial kidneys (WAKs) like AWAK have undergone initial human trials, with further study required for clinical implementation.
• Implantable artificial kidneys (IAKs) are biohybrid devices in preclinical testing, combining artificial filters with living cells.
• These portable devices potentially reduce reliance on water and electricity, facilitating home dialysis and self-care.

Conclusions:

• Wearable and implantable artificial kidneys represent promising innovations for ESRD management.
• These technologies may enhance the accessibility and desirability of self-care renal replacement therapy.
• Successful implementation could lead to reduced healthcare infrastructure costs associated with traditional dialysis facilities.
