Rotor Pumps for Artificial and Assisted Circulation
Biomedical Engineering, 2011The history of development of rotor pumps for artificial and assisted circulation is discussed in this work. Advantages of rotor pumps over pulsating pumps in implanted systems are considered: minimal size, energy consumption, and cost. Major directions in the development of rotor pumps include bearing elements, which determine pump service life. Axial

The Role of Assisted Circulation in Cardiac Resuscitation
JAMA: The Journal of the American Medical Association, 1966Heart-lung machines now used for cardiac surgery should be considered for use as an extended form of cardiopulmonary resuscitation in selected patients. Of eight patients in whom cardiac arrest had proved refractory to open- or closed-heart cardiac massage, all but one were resuscitated and survived hours to days. One patient recovered completely.

Assisted Circulation in Treatment of Experimental Heart Failure
Archives of Surgery, 1965WITH THE development of low-priming volume oxygenators, assisted circulation has become available for emergency use. It has been suggested as treatment for a number of conditions including septicemic shock, 1 cardiac arrest, 2,3 pulmonary insufficiency, 4 and congestive heart failure.

Modeling and Optimization of Assisted Circulation
IEEE Transactions on Biomedical Engineering, 1984Many methods of mechanical assistance to aid the failing heart have been, and are being, extensively investigated. The hemodynamic goals of the different methods being studied vary depending upon the specific patient problems, however, they all fit into three general categories: decreasing the work of the failing myocardium by reducing the load on the ...

Current left ventricular assist devices (LVADs) differ with respect to their pump characteristics as described by the pump characteristic curve (also called HQ-curve). Pressure sensitive LVADs depict a flat characteristic curve while most available LVADs
