    Researchers have developed miniaturized, programmable insulin delivery systems for long-term diabetes treatment. These safe and reliable devices offer improved options for ambulant and implantable patient care.

    Area of Science:

    • Biomedical Engineering
    • Medical Devices
    • Diabetes Technology

    Background:

    • Continuous development of program-controlled insulin delivery systems since 1972.
    • Need for miniaturized, reliable devices for ambulant and long-term diabetes management.

    Purpose of the Study:

    • To describe various alternatives for program-controlled insulin delivery systems.
    • To highlight technical improvements enabling ambulant and implantable use.
    • To summarize clinical trial experiences with these devices.

    Main Methods:

    • Development of fixed-programmable and demand-programmable devices in two parts (control and delivery units).
    • Miniaturization and technical improvements of electronic drive systems using CMOS technology.
    • Adaptation of mechanical components, including a stepping motor-driven roller pump, for implantable applications.
