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 ...

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.

Control issues in rotary heart assist devices
Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000Heart assist devices are mechanical pumps used in patients with cardiovascular diseases who are awaiting heart transplantation. With increasing clinical success, these devices are being used for longer periods of time, and automatic control has become an important requirement.

Early Clinical Experiences with a Heart Assist Device
1975A method of left heart (left atrium-aorta) support after open heart surgery is described. Thoracic reentry is not required when support is terminated. The system has been employed in 10 patients, 4 of whom are long-term survivors.

Implanted Heart Assist Device after Intracardiac Surgery
New England Journal of Medicine, 1974IN recent years there has been a steady decline in mortality after open intracardiac operations. However, persistent low cardiac output remains one of the prime causes of death, particularly in patients with far advanced myocardial dysfunction at the time of operation.

On-line pressure estimation for a left heart assist device
IEEE Transactions on Biomedical Engineering, 1990Long term measurement of blood pressures is essential for control of circulatory systems with artificial hearts or circulatory assist devices. Efforts to obtain reliable continuous direct measurements of blood pressures, however, have not been successful.

Flow Field of a Novel Implantable Valveless Counterpulsation Heart Assist Device [PDF]
Annals of Biomedical Engineering, 2012 Flow fields are one of the key factors associated with the life threatening formation of thrombi in artificial organs. Therefore, knowledge of flow field is crucial for the design and optimization of a long-term blood pump performance. The blood chamber flow of a novel counterpulsation heart assist device (CPD) has been investigated using laser Doppler

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.

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.

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 ...
