    Area of Science:

    • Biomedical Engineering
    • Cardiovascular Surgery

    Background:

    • Intracardiac surgery requires efficient blood oxygenation and temperature control.
    • Existing bubble oxygenators may present challenges in blood trauma and operational complexity.

    Purpose of the Study:

    • To develop and clinically evaluate a new bubble oxygenator for intracardiac surgery.
    • To assess the device's efficacy, safety, and ease of use in pediatric patients.

    Main Methods:

    • Development of a bubble oxygenator with a controllable blood-volume chamber, integrated heat exchanger, and a two-stage microfilter.
    • Clinical evaluation in 132 infantile and pediatric open heart procedures.
    • Assessment of embolic complications and physiological blood gas levels.

    Main Results:
