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 ...

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.

Right ventricular assist device thrombosis during biventricular heart assistance
Perfusion, 2004We report a case of total thrombosis of a right ventricular assist device in a patient during biventricular assistance. The thrombosis occurred 18 days following implantation and the right ventricular device was immediately removed without any complications. The patient was successfully transplanted after 3 months of left ventricular assistance.

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 ...

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.

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.

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.

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.

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 ...

A Fluidic Drive System for Intra-Aortic Balloon Heart Assist Device
IEEE Transactions on Biomedical Engineering, 1978Intra-aortic balloon pumping is a counter pulsation technique for temporary circulatory assistance in cardiogenic shock and other low cardiac output conditions. Conventional systems use a balloon at the end of a catheter driven by a solenoid valve, controlled by patient's ECG or ventricular pressure signal.
