Italian researchers developed electromechanical total artificial hearts (TAHs) and ventricular assist devices (VADs) using ball-screw technology. Early tests show promise for these advanced cardiac support systems.

Area of Science:

  • Biomedical Engineering
  • Cardiovascular Surgery
  • Medical Device Development

Background:

  • Italy initiated a special program to advance cardiology and cardiosurgery technologies.
  • Previous total artificial heart (TAH) and ventricular assist device (VAD) models were analyzed and developed.

Purpose of the Study:

  • To develop and test electromechanical TAH and VAD prototypes.
  • To implement a fill-sensor-free control scheme for artificial hearts.
  • To conduct anatomical fitting studies using 3D chest models.

Main Methods:

  • Development of a first prototype series using ball-screw actuation technology.
  • Preliminary bench testing and short-term animal implant experiments.
  • Utilizing a three-dimensional computer model for anatomical fitting.

Main Results:

  • Successful development of initial electromechanical TAH and VAD prototypes.
  • Completion of preliminary bench tests and short-term animal implantations.
  • Integration of a fill-sensor-free control scheme and anatomical fitting studies.

Conclusions:

  • The project successfully developed initial TAH and VAD prototypes with novel technology.
  • Ongoing development of second-generation prototypes for further testing.
  • The initiative demonstrates significant progress in Italian artificial heart research.
