Entwicklung der Atomvorstellung,plate-type blood pump and an actuator with a DC brushless motor and ball screw. For the reliability of the system, a minimal number of sensors are incorporated. Sixteen-bit and eight-bit microprocessors are used for the pump operation and motor speed control, respectively. The motor is driven by a w

Entwicklung der Atomvorstellung,d contamination through the shaft seal in direct motor drive. To overcome these problems, Baurmeister and Affeld proposed and developed a centrifugal pump with a.nutating (non rotating) impeller, the so-called tea spoon pump. However, a great reduction in hydrolysis is necessary with this pump. Pump

Grundlagen der Quantenmechanik,he blood pump are coated with either Cardiothane or Cardiomat. The system was tested in experiments on goats, whereby only one of fifteen animals showed sudden thrombus formation after 34 pumping days. The system was also applied in three clinical cases for durations of 18 h, 2 days, and 5 days. In

Grundlagen der Quantenmechanik,ormal and failing heart groups. RV function was evaluated hemodynamically and by a 2D echocardiography method. Incremental changes in LHB flow ratio from control, 25%, 50%, 75% to the maximum of 85%–100% resulted in decrements of the interventricular septum (IVS) segmental shortening fraction (SSF)
