    • The present invention provides an implantable, artificial ventricular assist device and system employing an undulation pump and methods for the use thereof. The undulation pump has a toroidal-shaped pump chamber with two angled side walls, an arc-shaped outer wall, an inlet port, an outlet port, and an inner circumferential opening and an undulation disk with a diameter that extends to about the arc-shaped outer wall of the pump chamber. The device includes a circumferential, flexible inner wall membrane covering the inner circumferential opening and least one surface of the undulation disk and forming liquid-tight seals to the pump chamber, or alternatively a precession assembly with inner bearings connected in series with an anti-rotation assembly, the anti-rotation assembly disposed within the pump and connected to the undulation disk, and preferably both, and a motor in connected communication with the precession assembly so that the disk undulates when motive force is applied.

    • A multi-step flow cleaning method and a multi-step flow cleaning apparatus are provided which effectively clean workpieces with a stream of a cleaning solution and to suppress an increase of foreign matters adhering to the surfaces of the workpieces. A cleaning tank 10 for holding workpieces is provided, a supply line 14 for supplying a cleaning solution such as pure water from the bottom surface of the cleaning tank is provided, and a valve 12 for adjusting the flow of the cleaning solution is disposed in the middle of the supply line 14. The valve 12 is equipped with a switching section 12a for controlling the outflow of the cleaning solution by opening or closing the supply line 14, and a bypass 12b for supplying the cleaning solution, bypassing the switching section 12a. The valve 12 is provided such that it is able to adjust in two steps the supply flow of the cleaning solution supplied to the cleaning tank 10 by using the supply flow fed through the bypass 12b and the supply flow fed through the switching section 12a.
