Multi-objective optimal control of a heart assist device
Proceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002Heart assist devices play an important role in the treatment of heart disease. One of the key issues with these devices is the control of pump speed to satisfy multiple clinical requirements such as providing adequate cardiac output at appropriate left atrial pressure and systolic arterial pressure.

Clinical Application of the Ellipsoid Left Heart Assist Device
Artificial Organs, 1978ABSTRACTThe ellipsoid left heart assist device (E‐LVAD) was implanted in eight patients suffering from intra‐operative heart failure. It was not possible to remove these patients from extracorporeal circulation following an intracardiac procedure; therefore, implantation of the E‐LVAD was performed during extracorporeal circulation.

Intelligent control design for heart assist devices
Proceedings of the 1998 IEEE International Symposium on Intelligent Control (ISIC) held jointly with IEEE International Symposium on Computational Intelligence in Robotics and Automation (CIRA) Intelligent Systems and Semiotics (ISAS) (Cat. No.98CH36262), 2002Heart assist devices are blood pumps used to augment the cardiac output of patients with left ventricular failure. A new generation of devices being evaluated for human use is based on turbo-hydrodynamic methods of pumping, which offer several advantages over the reciprocating, pulsatile methods used in current devices.

A new hydraulic heart assist device.
Life support systems : the journal of the European Society for Artificial Organs, 1986For the right drive of a hydraulic biventricular assist device (HBVAD), a new lightweight magnet with a permanent magnetic armature was constructed. A miniature optically incremental position sensor was developed, which is an integral part of the control loop of the driving unit, and was incorporated in the armature.
