RISA Note on the Leakage of the New Omniscience/tm Pivoting Disk Prosthetic Heart Valve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Measurements of the steady-state leakage of the new Medical Incorporated Omniscience/tm cardiac valve prosthesis are presented. These results are compared to those obtained from the SJM bi-leaflet ...
Estimation of the Rotational Undamped Natural Frequency of Bileaflet Cardiac Valve Prostheses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The angular momentum balance is solved numerically for a size 29 mm CarboMedics prosthetic heart valve. The lift force is estimated from potential flow theory, while the drag force is estimated ...
