摘要：
A pumping system 10, Figure 1 , provides a physiological pulsatile flow and includes controller 121, a pump drive head 50 coupled to a motor 12 and a fluid housing 52 having at least one port 60. The post 60 includes a ball valve retainer region 69, a valve seat 73, and an occlude ball 71 disposed in the ball valve retainer region 69. During operation, the motor 12 forces the fluid in and out the fluid housing 52 and causes the occlude ball 71 to move from a first position whereby the fluid cannot pass through the port 60, so a second position whereby the fluid moves annular to and generally around the occlude ball 71. This movement creates a slight flow reversal that "breaks up" any blood clots that may form. The pumping system may be used as part of a cardiopulmonary bypass system, a ventricular assist device (VAD) and/or a heart pump.
