Control of heart assist devices
42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004In this paper, we discuss several control techniques for Ventricular Assist Devices (VADs) and describe a hierarchical control structure that can be used to regulate the operation of a turbo-hydrodynamic VAD. Early assist devices were pulsatile, and control usually focused on regulating flow, atrial and/or arterial pressures.

Control of an extracorporeal heart assist device
2012 IEEE International Conference on Control Applications, 2012Heart assist devices provide mechanical circulatory support for patients with end-stage heart failure. Extracorporeal blood pumps are applied to adult and pediatric patients in the case of uni- and biventricular assistance. Modern driving units provide more mobility what is an immense benefit to the quality of life of the patients.

The Design of a Piezoelectric Heart Assist Device
IEEE Transactions on Biomedical Engineering, 1975A piezoelectric heart assist device was designed, and preliminary tests were performed in vitro and in vivo. The device has the advantages of simple construction, low power consumption (approximately one watt), electrical rather than pneumatic drive, and noiseless operation.

Experience with the Berlin Heart Assist Device
Artificial Organs, 1994Abstract: Different mechanical circulatory support systems (MCSS) have been in clinical use since 1987 to keep patients alive by assisting the heart during cardiac recovery after open heart surgery, myocardial infarction, acute graft failure after heart transplantation, or as a bridge to transplantation in heart transplant candidates.
