Access from EThOS:
The extent of blood damage within a ventricular assist device (VAD) is strongly dependent on the behaviour of blood flow within the device. In order to evaluate the flow behaviour of a pneumatically driven sac type VAD, a model circulation system was constructed; non-invasive diaphragm motion monitoring, mass transfer methods for wall shear distribution estimations, and other new techniques were developed; and extensive investigations were carried out. These include: (i) analysis of the effects of the system parameters, the operating and the load variables upon the dynamics of pumping; (ii) investigations of the velocity and stress distributions and fluid particle residence times within the device using a one-component laser Doppler anemometer (LDA), and employing flow visualisation and the newly developed techniques; and (iii) monitoring the motions of the pumping diaphragm, and analysing the effects of the motions upon the flow behaviour.
