The Influence of Mock Circulation Input Impedance on Valve Acceleration During In Vitro Cardiac Device Testing

Autor: George M. Pantalos, Guruprasad A. Giridharan, M. Keith Sharp, K J Gillars, Christopher M. Richards

Publikováno v: ASAIO Journal. 54:341-346

For a mechanical heart valve, a strong spike in pressure during closing is associated with valve wear and erythrocyte damage; thus, for valid in vitro testing, the mock circulation system should replicate the conditions, including pressure spikes, ex

Publikováno v: ASAIO journal (American Society for Artificial Internal Organs : 1992). 56(1)

A mock circulation system has been developed to approximate key anatomic features and simulate the pressures and flows of an infant. Pulsatile flow is generated by 10 cc pulsatile ventricles (Utah infant ventricular assist device). Systemic vasculatu
