1
Between the stator and impeller, a hydrodynamic bearing is formed.
2
In the device failure, trouble with hydrodynamic bearing was conspicuous.
3
Although instability of the hydrodynamic bearing should be improved, performance of the HFTAH with physiological control could be demonstrated.
4
The HeartWare HVAD is a radial rotary blood pump with a combination of passive magnetic and hydrodynamic bearings to levitate the impeller.
