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.

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.

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.

Heart assist devices: Modeling and diagnostics
2nd Middle East Conference on Biomedical Engineering, 2014In this paper, adaptive stead-state models are presented for axial flow-pumps used as heart assist devices. These models predict flow rate and power consumption of the pump based on the pressure differential (head) and impeller speed. The developed models are identified using system identification techniques on data obtained from a mock circulatory ...

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.

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.

Platelet Activation Markers in Patients With Heart Assist Device
Artificial Organs, 2005Abstract: Clinical use of heart assist devices is often associated with thromboembolic complications. We hypothesized that platelets may be activated in patients receiving assist devices and examined expression of the platelet activation markers CD62, CD63, and thrombospondin using flow cytometry in eight patients with Novacor left ventricular assist ...

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.

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 ...
