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 ).

Automatic monitoring of the infusion system in a rotary heart assist device
2003 IEEE 29th Annual Proceedings of Bioengineering Conference, 2003A fault detection algorithm was designed to monitor the infusion system of a ventricular assist device (AB-180 Circulatory Support System [AB-180 CSS], CardiacAssist, Inc.). This algorithm measures the infusion pressure, calculates the pressure derivative, and then compares to the preset thresholds to detect leaks and kinks in the infusion line ...
