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.

Modeling And Control Of An Extracorporeal Heart Assist Device
IFAC Proceedings Volumes, 2014Abstract Heart assist devices provide mechanical circulatory support for patients with end-stage heart failure. Extracorporeal heart assist devices 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 ...

Low cardiac output is a continuing cause of mortality after intracardiac operation in patients coming to surgery with advanced myocardial dysfunction. A simple method using a left heart assist device (LHAD) after open heart surgery to manage low cardiac output resistant to all adjuvant therapy is described.

The left ventricular assist device (LVAD) is a mechanical device implanted in patients with congestive heart failure to assist the heart in pumping blood through the circulatory system. The latest generation of this device is comprised of a rotary pump which is generally much smaller, lighter, and quieter than the first-generation conventional ...

A control oriented model design of heart assistant devices
IFAC Proceedings Volumes, 2011Abstract As a treatment option for patients with end-stage heart failure, mechanical circulatory support systems maintain the blood circulation in the human body. For biventricular assistance or for pediatric patients, paracorporeal pulsatile blood pumps are used.

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.
