The coiled envelope-a disposable insert for coil dialysis

Area of Science:

• Biomedical Engineering
• Nephrology
• Medical Device Development

Background:

• Dialysis is a critical treatment for kidney failure.
• Current commercial dialyzers often undergo reuse, posing challenges for sterilization and pyrogen control.
• There is a need for innovative dialysis solutions that enhance safety and reduce costs.

Purpose of the Study:

• To develop and characterize a novel disposable coiled envelope insert for coil dialysis.
• To evaluate the efficacy and design advantages of the new dialyzer system.
• To assess the clinical performance and cost-effectiveness of the disposable insert.

Main Methods:

• Development of the coiled envelope insert and associated hardware.
• In vitro and in vivo characterization of the dialyzer.
• Clinical trials involving patient dialysis procedures.

Main Results:

• The dialyzer demonstrated efficacy in clinical studies.
• The device can be assembled in under 5 minutes.
• Disposable blood fluid path materials can be certified sterile and pyrogen-free for each use.

Conclusions:

• The coiled envelope dialyzer offers a safe and effective alternative to reusable devices.
• The disposable design provides advantages in sterility assurance and assembly time.
• The projected cost is approximately half that of current commercial dialyzers, offering economic benefits.
