    摘要： A pump includes a flexible conduit, at least one valve attached to the flexible conduit about the perimeter of the valve; and a drive mechanism to move the valve to pump blood within the conduit. The drive mechanism can, for example, be adapted to complete a single stroke during each heart ventricle contraction and/or to complete multiple strokes (that is, oscillate) during a single contraction. Another implantable pump for assisting blood flow, includes: a flexible conduit formed in an arc; at least one movable valve in operative connection with the conduit; and a drive mechanism to move the valve in an arced path to pump blood within the conduit. Another pump includes a conduit and at least one moveable valve within the conduit. The moveable valve includes a plurality of openings. Each of the plurality of openings has a closure mechanism in operative connection therewith. Each closure mechanism is operable to at least partially close the opening to which it is operatively connected when the moveable valve is moved forward and to open the opening to which it is operatively connected when the valve is move rearward. The pump further includes a drive mechanism to move the valve to pump blood within the conduit. In one embodiment, each closure mechanism includes a flap of resilient material.

    摘要翻译： 泵包括柔性导管，至少一个阀，围绕阀的周边连接到柔性导管; 以及驱动机构，用于移动阀以泵送导管内的血液。 例如，驱动机构可以适于在每次心室收缩期间完成单个冲程和/或在单次收缩期间完成多个冲程（即，振荡）。 另一种用于辅助血液流动的植入式泵，包括：形成为弧形的柔性导管; 至少一个与所述导管可操作地连接的活动阀; 以及驱动机构，用于使所述阀在弧形路径中移动以在所述导管内泵送血液。 另一泵包括管道和管道内的至少一个可动阀。 可移动阀包括多个开口。 多个开口中的每一个具有与其可操作连接的闭合机构。 当可移动阀向前移动时，每个闭合机构可操作以至少部分地关闭其可操作地连接的开口，并且当阀向后移动时打开其可操作地连接的开口。 泵还包括驱动机构，以使阀移动以泵送导管内的血液。 在一个实施例中，每个闭合机构包括弹性材料的翼片。
