    Area of Science:

    • Biomedical Engineering
    • Endocrinology
    • Medical Devices

    Background:

    • Conventional insulin injection methods (single or multiple) present limitations in achieving optimal glycemic control.
    • The need for more precise and adaptable insulin delivery methods is critical for diabetes management.

    Purpose of the Study:

    • To present the characteristics of electronically controlled insulin delivery systems.
    • To evaluate the potential of these systems in improving glycemic control.
    • To report on the development and initial testing of an implantable insulin delivery system.

    Main Methods:

    • Review and presentation of the design and functionality of electronically controlled insulin delivery systems.
    • Analysis of early experimental results from external insulin delivery systems.

  • Development and preliminary testing of an implantable insulin delivery system in canine subjects.

    • Main Results:

    • Early experiments with external systems demonstrated improved glycemic control compared to conventional methods.
    • An implantable system with remote controls for variable insulin flow rates has been developed and initially tested.
    • Engineering aspects of these insulin delivery systems do not appear to present major development problems.

    Conclusions:

    • Electronically controlled insulin delivery systems, both external and implantable, hold significant promise for enhanced diabetes management.
    • Further research and experimentation are required to address remaining questions before widespread clinical adoption.
    • The engineering feasibility of advanced insulin delivery systems is established, paving the way for future development.
