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.

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 ...

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 ...

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.

Technique and results with a roller pump left and right heart assist device
The Annals of Thoracic Surgery, 1989During the last 10 years we have inserted a roller pump-driven left heart assist device in 72 patients and a right heart assist device in 7 patients for profound heart failure after a variety of cardiac surgical procedures. In addition a percutaneous left heart assist device (transseptal insertion of left atrial cannula via a femoral vein) was employed

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.

An Ambulatory Pulmonary and Right Heart Assist Device (OxyRVAD) in an Ovine Survival Model
The Journal of Heart and Lung Transplantation, 2007To develop ambulatory total respiratory and right heart assistance for up to 4 weeks as a bridge to lung transplantation, we coupled a compact gas exchange device with a right ventricular assist device (RVAD), a compact rotary blood pump, to create an "OxyRVAD."Our ambulatory OxyRVAD includes a portable (4 x 4 x 7-cm) centrifugal pump with heparin ...

Circulatory Assistance: Basic Classification of Heart Assistance Methods and Devices
Biocybernetics and Biomedical Engineering, 2011This paper is focused on basic classification of mechanical circulatory assistance methods and devices regarding a way of their connection to the circulatory system (parallel, “in-series”), different manner of work (pulsatile, continuous-flow) or a goal of appliance ( bridge to recovery, bridge to transplant, Total Artificial Heart ).
