    A new wearable, battery-powered pneumatic pump for total artificial heart (TAH) systems demonstrates high efficiency and adaptability. Animal tests confirm its capability to support circulation in large calves, ensuring adequate blood supply and balance.

    Area of Science:

    • Biomedical Engineering
    • Cardiovascular Devices
    • Artificial Organs

    Background:

    • Total artificial heart (TAH) systems are crucial for end-stage heart failure.
    • Efficient and adaptable drive units are essential for TAH device performance.
    • Wearable, batter-powered solutions are needed for improved patient mobility.

    Purpose of the Study:

    • To present a novel pneumatic, wearable, battery-powered TAH-drive unit.
    • To evaluate the efficiency and control system of the TAH-drive unit.
    • To assess the device's performance in supporting circulatory needs in animal models.

    Main Methods:
