ABSTRACT OF THE DISCLOSURE A pulsatile flow delivery apparatus includes a pump, an elastic tube, an occlusive clamp and a control device. The elastic tube is connected to the pump, and at least a part of it is made of a material with a rubber hardness code of no greater than 70° (JIS). The clamp is placed on the outlet of the tube for opening and closing its outlet, and a control device is connected to the clamp for controlling the timing for opening and closing of the clamp to convert the continuous flow produced by the pump into a pulsatile flow. Another pulsatile flow delivery apparatus includes a horse shoe shaped raceway, a tube of a material with a rubber hardness code of no greater than 70° (JIS), a milking mechanism, an occlusive clamp and a control device. The tube is disposed along the raceway. The milking mechanism has a pivot shaft, a rotating arm fixedly secured to the shaft and one milking roller rotatably mounted on one end of the rotating arm. The timing of opening and closing of the occlusive clamp is controlled by the control device to produce a pulsatile flow. -37-
