A new portable driver for the Cleveland Clinic Foundation (CCF) left ventricular assist device (LVAD) offers cardiac patients increased mobility. This compact, lightweight system provides 2 hours of freedom from a fixed driver, using standard technology.

Area of Science:

  • Biomedical Engineering
  • Cardiovascular Technology
  • Medical Device Development

Background:

  • The Cleveland Clinic Foundation (CCF) left ventricular assist device (LVAD) is a single-chamber pump.
  • Current LVAD systems often require patients to remain tethered to bulky, stationary drivers.
  • Limited mobility significantly impacts the quality of life for patients requiring mechanical circulatory support.

Purpose of the Study:

  • To develop a low-cost, portable driver for the CCF LVAD.
  • To enhance patient mobility and freedom of movement.
  • To provide a practical solution for ambulatory LVAD patients.

Main Methods:

  • Design and fabrication of a compact and lightweight driver unit.
  • Integration of a high-pressure pneumatic cylinder for LVAD operation.

Related Experiment Videos

  • Testing of the portable driver's performance and duration of untethered use.

    • Main Results:

    • A functional, low-cost, and portable driver for the CCF LVAD was successfully developed.
    • The driver enables approximately 2 hours of freedom from a fixed position.
    • The system utilizes readily available, non-exotic technology, facilitating wider adoption.

    Conclusions:

    • The developed portable driver significantly improves mobility for patients with pneumatic LVADs.
    • This innovation offers a more convenient and less restrictive option for cardiac care.
    • The system represents a step forward in improving the quality of life for LVAD recipients.
