https://doi.org/10.1007/978-3-642-40615-7In the recent past, several attempts have been made to develop rotary or nonpulsatile implantable blood pumps for assisted circulation . We, too, are engaged in constructing such a device with a design basically identical to that of our 16th prototype of the known spindle pump (Fig. 1).

Questions and Predictions., “Questions and Predictions” concerned what was best: a left ventricular assist device (LVAD) or a total artificial heart (TAH). For those patients a waiting a transplant, the outcome for LVADs or TAHs is about the same, provided one is prepared to use a right ventricular assist device (RVAD) too, when the LVAD alone cannot cope.

David Aspinall,Patrick Maier,Ian Starkle in the ejection phase and to increase the myocardial blood supply in the filling phase of the heart. Due to the fact that counterpulsation works in series for the natural heart, the devices are up to 25% effective and depend on a certain amount of residual minimal circulation. In cases of complet

Formal Methods for Components and Objectsiac cycles, systolic and diastolic. It derived from the observation that myocardial oxygen consumption depends on the myocardial time-tension index . If, therefore, pressure during ventricular ejection could be reduced, oxygen consumption could also be reduced, provided mean arterial perfusion pr

An optimal relationship between left ventricular geometry and capacity on the one hand and intraventricular balloon shape and volume on the other appears to exist . The selection of an optimal balloon shape and volume is not

Property-Based Testing - The ProTest Projectality was near 10%. The designs of the pulsatile devices have not changed very much, being basically membrane pumps available in the form of a sac (Portner) or a moving diaphragm (Pierce, Unger, Frazier, Whalen) (Table 1). The driving source is either pneumatic or electromechanical via a tube throug
